[PATCH v7 4/4] dm: Remove unused macro DM_ZONE_INVALID_WP_OFST

[Damien Le Moal <dlemoal@kernel.org>]

With the switch to using the zone append emulation of the block layer
zone write plugging, the macro DM_ZONE_INVALID_WP_OFST is no longer used
in dm-zone.c. Remove its definition.

Fixes: f211268ed1f9 ("dm: Use the block layer zone append emulation")
