scsi: ibmvfc: add NVMe/FC Implicit Logout and Move Login support

Browse Source 
Add protocol-specific handling for implicit logout and move-login
operations on NVMe/FC targets.

Select the NVMe/FC-specific implicit logout opcode when operating on an
NVMe target and update the associated logging so protocol-specific
operations are visible in debug output. This extends the existing target
relogin and migration-related flows to work with NVMe targets as well as
SCSI targets.

These changes are needed so target reauthentication and target movement
continue to work once NVMe/FC targets are added to the driver's state
machine.
