Subject[PATCH] arm: decompressor: mark error() as __noreturn
gcc complains about fortify_panic() possibly returning:

arch/arm/boot/compressed/misc.c: In function 'fortify_panic':
arch/arm/boot/compressed/misc.c:167:1: error: 'noreturn' function does return [-Werror]

This annotates the error() function as __noreturn, which lets gcc
see in all configurations that it fortify_panic() cannot return either.

Fixes: ee333554fed5 ("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
