Subject: [PATCH AUTOSEL 6.14 567/642] scsi: lpfc: Reduce log message generation during ELS ring clean up

From: Justin Tee <justin.tee@...adcom.com>

[ Upstream commit 8eccc58d71eafbd2635077916b68fda15791d270 ]

A clean up log message is output from lpfc_els_flush_cmd() for each
outstanding ELS I/O and repeated for every NPIV instance.  The log message
should only be generated for active I/Os matching the NPIV vport.  Thus,
move the vport check to before logging the message.
