Currently the FC-NVMe driver is leverating the SCSI FC transport class to
access the remote ports. Which means that all FC-NVMe remote ports will be
visible to the fc transport layer, but due to missing definitions the port
roles will always be 'unknown'. This patch adds the missing definitions to
the fc transport class to that the port roles are correctly displayed.

qla2x00_init_timer() calls add_timer() on the iocb timeout timer, which
means the timeout function pointer and any data that the function depends on
must be initialised beforehand.
Move this initialisation before each call to qla2x00_init_timer(). In some
cases qla2x00_init_timer() initialises a completion structure needed by the
timeout function, so move the call to add_timer() after that.

When connection type is N_Port to N_Port (point-to-point), there

port name sends the PLOGI but not allow to send PRLI if is a

Current driver code deletes old session when it receives PLOGI
request. If we will not receive PLOGI request then we will not
delete old session and create new session. Add check for N2N
with PRLI receive only and trigger cleanup. For this case, the
cleanup requires individual cmd abort instead of using implicit
