Subject: scsi: qla2xxx: Replace vmalloc + memset with vzalloc
Patch-mainline: v5.4-rc1
Git-commit: 56cc8fae5f7e9f38cb367754c52491ba1645d1bf
References: bsc#1082635 bsc#1141340 bsc#1143706
Use vzalloc instead of using vmalloc to allocate memory and then zeroing it
with memset. This simplifies the code.
