cmd: disk: Fix unused variable warning
If serial support is not compiled into U-Boot, which may be the case for some SPL builds, the following warning will be generated in disk.c: cmd/disk.c: In function 'common_diskboot': cmd/disk.c:16:6: warning: variable 'dev' set but not used [-Wunused-but-set-variable] int dev, part; ^ The warning is a result of printf() calls being optimized away, and thus the whole dev variable becomes indeed unused. Mark the variable as __maybe_unused .
