Subject: mm/mprotect.c: optimize error detection in do_mprotect_pkey()
Obviously, the error variable detection of the if statement is
for the mprotect callback function, so it is also put into the
scope of calling callbck.
This is a cleanup which makes this site consistent with the rest of this
function's error handling.
