Subject: scsi: qla2xxx: Make qla2x00_abort_srb() again decrease the sp
reference count
Patch-mainline: v5.4-rc1
Git-commit: d2d2b5a5741d317bed1fa38211f1f3b142d8cf7a
References: bsc#1143706 bsc#1123034 bsc#1131304 bsc#1127988
Since qla2x00_abort_srb() starts with increasing the reference count of
@sp, decrease that same reference count before returning.
