devmapper: fix reloadPool() to also specify '1 skip_block_zeroing'

Browse source 
createPool() and reloadPool() should be consistent with the thin-pool
table params they use.

Since createPool() specifies '1 skip_block_zeroing' reloadPool() should
too.  Otherwise, if the pool is reloaded (as is done when resizing
loopback devices) block zeroing will be enabled after the reload
completes.
