  From: Arnd Bergmann <arnd@arndb.de>

The newly introduced selftest function causes a warning when -Wmissing-prototypes
is enabled:

arch/x86/kernel/alternative.c:1461:32: error: no previous prototype for '__alt_reloc_selftest' [-Werror=missing-prototypes]

Since it's only used locally, add the prototype directly in front of it.

Fixes: 270a69c4485d ("x86/alternative: Support relocations in alternatives")
