Patch series "maple_tree: simplify mas_push_node()", v2.

When count is not 0, we know head is valid.  So we can put the assignment
in if (count) instead of checking the head pointer again.

Also count represents current total, we can assign the new total by
increasing the count by one.


This patch (of 3):

If this is not a new allocated one, the request_count has already been
cleared in mas_set_alloc_req().
