    selftests/x86/pkeys: Remove unused functions
    
    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);
         ^~~~~~~~~~~~~~~~~~~~~~
