scsi: tracing: Fix compile error in trace_array calls when TRACING is disabled
Fix this compilation error seen when CONFIG_TRACING is not enabled:
drivers/scsi/qla2xxx/qla_os.c: In function 'qla_trace_init':
drivers/scsi/qla2xxx/qla_os.c:2854:25: error: implicit declaration of function
'trace_array_get_by_name'; did you mean 'trace_array_set_clr_event'?
[-Werror=implicit-function-declaration]
2854 | qla_trc_array = trace_array_get_by_name("qla2xxx");
| ^~~~~~~~~~~~~~~~~~~~~~~
| trace_array_set_clr_event
drivers/scsi/qla2xxx/qla_os.c: In function 'qla_trace_uninit':
drivers/scsi/qla2xxx/qla_os.c:2869:9: error: implicit declaration of function
'trace_array_put' [-Werror=implicit-function-declaration]
2869 | trace_array_put(qla_trc_array);
| ^~~~~~~~~~~~~~~
