x86/boot: Declare error() as noreturn
The compressed boot function error() is used to halt execution, but it
wasn't marked with "noreturn". This fixes that in preparation for
supporting kernel FORTIFY_SOURCE, which uses the noreturn annotation
on panic, and calls error(). GCC would warn about a noreturn function
calling a non-noreturn function:
arch/x86/boot/compressed/misc.c: In function ‘fortify_panic’:
arch/x86/boot/compressed/misc.c:416:1: warning: ‘noreturn’ function does return
}
