SCSI: qla2xxx: fix error handling of qla2x00_mem_alloc()
commit b2a72ec32d0f499aaadf41264232517a12326df0 upstream.
qla2x00_mem_alloc() returns 1 on success and -ENOMEM on failure. On the
one hand the caller assumes non-zero is success but on the other hand
the caller also assumes that it returns an error code.
I've fixed it to return zero on success and a negative error code on
failure. This matches the documentation as well.
