selftests/x86/pkeys: Remove unused functions
commit ce676638fe7b284132a7d7d5e7e7ad81bab9947e upstream.
This also gets rid of two build warnings:
protection_keys.c: In function ‘dumpit’:
protection_keys.c:419:3: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]
write(1, buf, nr_read);
