dm: verity-loadpin: Drop use of dm_table_get_num_targets()

Browse source 
Commit 2aec377a29 ("dm table: remove dm_table_get_num_targets()
wrapper") in linux-dm/for-next removed the function
dm_table_get_num_targets() which is used by verity-loadpin. Access
table->num_targets directly instead of using the defunct wrapper.

Fixes: b6c1c5745c ("dm: Add verity helpers for LoadPin")
