hw/block/nvme: harden cmb access

Since the controller has only supported PRPs so far it has not been
required to check the ending address (addr + len - 1) of the CMB access
for validity since it has been guaranteed to be in range of the CMB.

This changes when the controller adds support for SGLs (next patch), so
add that check.
