From: Vasu Dev <vasu....@intel.com>
Currently fc_host mfs is not getting updated in
case its changed during FLOGI and that leaves fc_host
to show its initial old value in sysfs, so instead
have fc_host mfs updated along with updating lport mfs
during FLOGI.
Also in case of bad mfs during flogi, error out
instead of continuing with flogi.
[ Changes made by Robert Love: condition to '>=' and
added printing of lport->mfs in DBG statement. FLOGI
resp processing failed without being able to compare
FCoE MFS 2112 against an incoming MFS of 2112 ]
