Subject: scsi: lpfc: Reduce time spent in IRQ for received NVME commands
Patch-mainline: v4.13-rc1
Git-commit: 810ffa4789c8453caf0b876619c428bf64fef304
References: bsc#1050239,FATE#322918

Removed unnecessary bzero of context area. Due to size of sg list, added
a substantial delay and played havoc on cpu caches.
