x86/paravirt: Mark unused patch_default label
A bugfix commit:
45dbea5f55c0 ("x86/paravirt: Fix native_patch()")
... introduced a harmless warning:
arch/x86/kernel/paravirt_patch_32.c: In function 'native_patch':
arch/x86/kernel/paravirt_patch_32.c:71:1: error: label 'patch_default' defined but not used [-Werror=unused-label]
Fix it by annotating the label as __maybe_unused.
