[PATCH] scsi: esas2r: fix __printf annotation on esas2r_log_master()

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

clang-22 started warning about functions that take printf format strings:

drivers/scsi/esas2r/esas2r_log.c:160:50: error: diagnostic behavior may be improved by adding the 'format(printf, 3, 0)' attribute to the declaration of 'esas2r_log_master' [-Werror,-Wmissing-format-attribute]
  121 |                 retval = vsnprintf(buffer, buflen, format, args);
      |                                                                ^
drivers/scsi/esas2r/esas2r_log.c:121:12: note: 'esas2r_log_master' declared here
  121 | static int esas2r_log_master(const long level,
      |            ^

The warning already got silenced for gcc but not clang in the past.
Rather than modify that hack to turn it off for both, just add the
attribute as suggested and remove the pragma again.
