fscrypt: remove unnecessary checks for NULL operations
The functions in fs/crypto/*.c are only called by filesystems configured with encryption support. Since the ->get_context(), ->set_context(), and ->empty_dir() operations are always provided in that case (and must be, otherwise there would be no way to get/set encryption policies, or in the case of ->get_context() even access encrypted files at all), there is no need to check for these operations being NULL and we can remove these unneeded checks.
