mm: cleanup vma_iter_bulk_alloc

commit d24062914837 ("fork: use __mt_dup() to duplicate maple tree in
dup_mmap()"), removed the only user and mas_expected_entries has been
removed, since commit e3852a1213ffc ("maple_tree: Drop bulk insert
support").  Also cleanup the mas_expected_entries in maple_tree.h.

No functional change.
