Fix following trivial build warning:
drivers/md/dm-cache-target.c:2182:13: warning:
‘too_many_discard_blocks’ defined but not used [-Wunused-function]
static bool too_many_discard_blocks(sector_t discard_block_size,
^
It's usage removed by ab1f4c35b7("dm cache: prevent corruption caused by
discard_block_size > cache_block_size") as work-around and the
definition was not removed though it was only one usage. Let's remove
the definition now for clean build result and get back the definition
again after the workarounded problem solved well.
