dm table: fail dm_table_create on dm_round_up overflow
commit 5b2d06576c5410c10d95adfd5c4d8b24de861d87 upstream.
The dm_round_up function may overflow to zero. In this case,
dm_table_create() must fail rather than go on to allocate an empty array
with alloc_targets().
This fixes a possible memory corruption that could be caused by passing
too large a number in "param->target_count".
