mm: fix xyz_noprof functions calling profiled functions
Grepping /proc/allocinfo for "noprof" reveals several xyz_noprof
functions, which means internally they are calling profiled functions.
This should never happen as such calls move allocation charge from a
higher level location where it should be accounted for into these lower
level helpers. Fix this by replacing profiled function calls with noprof
ones.
