mm/mmap: remove preallocation from do_mas_align_munmap()

In preparation of passing the vma state through split, the pre-allocation
that occurs before the split has to be moved to after.  Since the
preallocation would then live right next to the store, just call store
instead of preallocating.  This effectively restores the potential error
path of splitting and not munmap'ing which pre-dates the maple tree.
