x86, fpu: check __clear_user() return value

fix warning:

  arch/x86/kernel/xsave.c: In function ‘save_i387_xstate’:
  arch/x86/kernel/xsave.c:98: warning: ignoring return value of ‘__clear_user’, declared with attribute warn_unused_result

check the return value and act on it. We should not be ignoring faults
at this point.
