[U-Boot] [PATCH V3 04/10] fat: ff: add ifdef to avoid unused function warning

[Stephen Warren]

Without this, any board that doesn't enable read-write FAT triggers:
fs/fat/ff.c:1331:6: warning: ‘gen_numname’ defined but not used [-Wunused-function]

... since gen_numname() is not referenced from dir_register() is ifdef'd
out.
