mm/gup: Let __get_user_pages_locked() return -EINTR for fatal signal
__get_user_pages_locked() will return 0 instead of -EINTR after commit
4426e945df588 ("mm/gup: allow VM_FAULT_RETRY for multiple times") which
added extra code to allow gup detect fatal signal faster.
Restore the original -EINTR behavior.
