[PATCH] x86: boot: add a missing fallthrough statement

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

This instance seems to have slipped through the mass
conversions to the fallthrough keyword:

arch/x86/boot/printf.c:248:31: error: this statement may fall through [-Werror=implicit-fallthrough=]
