Wipe initial 4KiB for non-zeroed thin volumes
If the thin pool has disabled zeroing (created with -Zn), we at least clear initial 4KiB of such thin volume (provisions 1st block). If lvcreate is executed with '-an' command will abort (same way like we for normal LV - however for normal LV option -Zn may skip clearing completely, for thin volumes this option is not supported (applies only for pools).
