x86/paravirt: Mark unused patch_default label 

A bugfix commit:

  45dbea5f55 ("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.
