x86: move stac/clac from user copy routines into callers

This is preparatory work for inlining the 'rep movs' case, but also a
cleanup. The __copy_user_nocache() function was mis-used by the rdma
code to do uncached kernel copies that don't actually want user copies
at all, and as a result doesn't want the stac/clac either.
