In the function sli_xmit_bls_rsp64_wqe(), the 'if' and 'else' conditions
evaluates the same expression and give the same output. Also, params->s_id
shall not be equal to U32_MAX. Remove the unused code.
This fixes coccinelle warning such as:
drivers/scsi/elx/libefc_sli/sli4.c:2320:2-4: WARNING: possible
condition with no effect (if == else)

Pull SCSI updates from James Bottomley:
"This series consists of the usual driver updates (qla2xxx, pm8001,
libsas, smartpqi, scsi_debug, lpfc, iscsi, mpi3mr) plus minor updates
and bug fixes.
The high blast radius core update is the removal of write same, which
affects block and several non-SCSI devices. The other big change,
which is more local, is the removal of the SCSI pointer"

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

dma_alloc_coherent() ignores the zone specifiers so this is pointless and

'sli4->ext[i].use_map' is a bitmap. Use 'bitmap_zalloc()' to simplify code,
improve the semantic and avoid some open-coded arithmetic in allocator
arguments.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.

Flags value is being set to a constant and ANDed with 0 which always
results in 0.

This is the initial patch for the new Emulex target mode SCSI driver.
- Create the new Emulex source level directory drivers/scsi/elx and add
the directory to the MAINTAINERS file.
- Create the first library subdirectory drivers/scsi/elx/libefc_sli. This
library is a SLI-4 interface library.
- Start the population of the libefc_sli library with definitions of SLI-4
hardware register offsets and definitions.
