Subject: [PATCH 32/40] scsi: esas2r: esas2r: Add braces around the one-line if()

In certain configurations esas2r_bugon() is sometimes NULLed by the compiler.

Fixes the following W=1 kernel build warning(s):

 In file included from drivers/scsi/esas2r/esas2r_log.c:44:
 drivers/scsi/esas2r/esas2r.h: In function ‘esas2r_rq_init_request’:
 drivers/scsi/esas2r/esas2r.h:1229:17: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
 1229 | esas2r_bugon();
 | ^
 NB: Lots of these - snipped for brevity
