target: Add range checking to UNMAP emulation
commit 2594e29865c291db162313187612cd9f14538f33 upstream.
When processing an UNMAP command, we need to make sure that the number
of blocks we're asked to UNMAP does not exceed our reported maximum
number of blocks per UNMAP, and that the range of blocks we're
unmapping doesn't go past the end of the device.
