x86/quirks: Hide maybe-uninitialized warning

gcc -Wmaybe-uninitialized detects that quirk_intel_brickland_xeon_ras_cap
uses uninitialized data when CONFIG_PCI is not set:

arch/x86/kernel/quirks.c: In function âquirk_intel_brickland_xeon_ras_capâ:
arch/x86/kernel/quirks.c:641:13: error: âcapid0â is used uninitialized in this function [-Werror=uninitialized]

However, the function is also not called in this configuration, so we
can avoid the warning by moving the existing #ifdef to cover it as well.
