scsi: qla2xxx: Fix set-but-not-used variable warnings
[ Upstream commit 4fb2169d66b837a2986f569f5d5b81f79e6e4a4c ]
Fix the following two compiler warnings:
drivers/scsi/qla2xxx/qla_init.c: In function ‘qla24xx_async_abort_cmd’:
drivers/scsi/qla2xxx/qla_init.c:171:17: warning: variable ‘bail’ set but not used [-Wunused-but-set-variable]
171 | uint8_t bail;
| ^~~~
drivers/scsi/qla2xxx/qla_init.c: In function ‘qla2x00_async_tm_cmd’:
drivers/scsi/qla2xxx/qla_init.c:2023:17: warning: variable ‘bail’ set but not used [-Wunused-but-set-variable]
2023 | uint8_t bail;
| ^~~~
