A PCI function reset implies a temporary disappearance of a fc_rport.  So,
call lpfc_scsi_dev_block, which sets all mapped fc_rports into the
temporary FC_PORTSTATE_BLOCKED state.  Once PCI function reset completes
and link reinitialized, the fc_rport is rediscovered and
FC_PORTSTATE_BLOCKED state is removed.
