bdev: free bdev_io in write_zeroes emulation



When emulating write_zeroes commands on device that
don't natively support it, we submit a write with
a zeroed buffer.  We used to just reuse the original
bdev_io, but that was recently changed due to other
splitting code added for iovs.  But when making those
changes, we forgot to free the bdev_io for the
write that was sent down to the device.

Fixes: 183f37e8 (bdev: do not reuse bdev_io when...)
