YueHaibing 2397134ce2 x86/platform/pcspeaker: Use PTR_ERR_OR_ZERO() to fix ptr_ret.cocci warning
The ptr_ret.cocci script generates the following warning:

  arch/x86/kernel/pcspeaker.c:12:8-14: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO() rather than an open-coded version to fix this.
