mm/mremap: simplify vma expansion again

Browse source

This effectively reverts d014cd7c1c ("mm, mremap: fix mremap() expanding
for vma's with vm_ops->close()").  After the recent changes, vma_merge()
is able to handle the expansion properly even when the vma being expanded
has a vm_ops->close operation, so we don't need to special case it
anymore.
