block: check for RESIZE blocker in the QMP command, not bdrv_truncate()
If we check for the RESIZE blocker in bdrv_truncate(), that means a
commit will fail if the overlay layer is larger than the base, due to
the backing blocker.
This is a regression in behavior from 2.0; currently, commit will try to
grow the size of the base image to match the overlay size, if the
overlay size is larger.
By moving this into the QMP command qmp_block_resize(), it allows
usage of bdrv_truncate() within block jobs.
