dm table: Fix W=1 build warning when mempool_needs_integrity is unused

Browse Source 
The mempool_needs_integrity is unused. This, in particular, prevents
kernel builds with Clang, `make W=1` and CONFIG_WERROR=y:

drivers/md/dm-table.c:1052:7: error: variable 'mempool_needs_integrity' set but not used [-Werror,-Wunused-but-set-variable]
 1052 |         bool mempool_needs_integrity = t->integrity_supported;
      |              ^

Fix this by removing the leftover.
