mm/mmap: Don't adjust next for maple tree operations.

As maple tree store operation will alter the start location of the next
node if it they overlap, there is no need to erase and store the same
VMA.  In fact, since the start location is now occupied by the current
VMA, the erase operation will remove the wrong entry.
