x86/uaccess: Fix up the fixup

[ Upstream commit b69656fa7ea2f75e47d7bd5b9430359fa46488af ]

New tooling got confused about this:

  arch/x86/lib/memcpy_64.o: warning: objtool: .fixup+0x7: return with UACCESS enabled

While the code isn't wrong, it is tedious (if at all possible) to
figure out what function a particular chunk of .fixup belongs to.

This then confuses the objtool uaccess validation. Instead of
returning directly from the .fixup, jump back into the right function.
