mm, madvise: use standard madvise locking in madvise_set_anon_name()
Use madvise_lock()/madvise_unlock() in madvise_set_anon_name() in the same
way as in do_madvise(). This narrows the lock scope a bit and reuses
existing functionality. get_lock_mode() already picks the correct
MADVISE_MMAP_WRITE_LOCK mode for __MADV_SET_ANON_VMA_NAME so we can just
remove the explicit assignment.
There is a user visible change in that the prctl(PR_SET_VMA,
PR_SET_VMA_ANON_NAME...) might now return -EINTR.
