Subject: [PATCH] scsi: lpfc: Fix alloc context on oas lun creations
References: bsc#1136217,jsc#SLE-4722
Git-commit: 2d71dc8eb6e826f42f5dd0c8e005044a65c1da8b
Patch-mainline: v5.3-rc1

Softlockups are seen in low memory situations. They are due to doing
oas_lun allocation with GFP_KERNEL in atomic contexts.

Change the calls to oas_lun to indicate atomic context so that GFP_ATOMIC
is used.
