block: ublk: make sure that block size is set correctly
[ Upstream commit 1d1665279a845d16c93687389e364386e3fe0f38 ]
block size is one very key setting for block layer, and bad block size
could panic kernel easily.
Make sure that block size is set correctly.
Meantime if ublk_validate_params() fails, clear ub->params so that disk
is prevented from being added.
