	IB/uverbs: Prevent integer overflow in ib_umem_get address arithmetic

	Properly verify that the resulting page aligned end address is larger
	than both the start address and the length of the memory area requested.

	Both the start and length arguments for ib_umem_get are controlled by
	the user. A misbehaving user can provide values which will cause an
	integer overflow when calculating the page aligned end address.

	This overflow can cause also miscalculation of the number of pages
	mapped, and additional logic issues.
