clang-18 has improved its support for detecting operations that will
truncate values at runtime via -wfortify-source resulting in two new
warnings (or errors with CONFIG_WERROR=y):

  drivers/scsi/myrb.c:1906:10: warning: 'snprintf' will always be
  truncated; specified size is 32, but format string expands to at least
  34 [-Wfortify-source]

  drivers/scsi/myrs.c:1089:10: warning: 'snprintf' will always be
  truncated; specified size is 32, but format string expands to at least
  34 [-Wfortify-source]

When we have a string literal that does not contain any format flags,
rather than use snprintf (sometimes with a size that's too small), let's
use sprintf.

This is pattern is cleaned up throughout two files.
