dm-verity: fix dm_is_verity_target() when dm-verity is builtin

Browse source

commit 3708c72695 upstream.

When CONFIG_DM_VERITY=y, dm_is_verity_target() returned true for any
builtin dm target, not just dm-verity.  Fix this by checking for
verity_target instead of THIS_MODULE (which is NULL for builtin code).
