[SCSI] libfc: add FLOGI state to rport for VN2VN
The FIP proposal for VN_port to VN_port point-to-multipoint
operation requires a FLOGI be sent to each remote port.
The FLOGI is sent with the assigned S_ID and D_IDs of the
local and remote ports. This and the response get
FIP-encapsulated for Ethernet.
Add FLOGI state to the remote port state machine.
This will be skipped if not in point-to-multipoint mode.
To reduce a little duplication between PLOGI and FLOGI
response handling, added fc_rport_login_complete(), which
handles the parameters for the rdata struct.
