From: Leon Romanovsky <leonro@xxxxxxxxxx>
The mlx4 and mlx5 implemented differently the WQ input checks.
Instead of duplicating mlx4 logic in the mlx5, let's prepare
the input in the central place.
Fixes: f213c0527210 ("IB/uverbs: Add WQ support")
Reported-by: Jiapeng Chong <jiapeng.chong@xxxxxxxxxxxxxxxxx>

Changelog:
v1:
* Removed IB_WQS_RESET state checks because it is zero and wq states
declared as u32, so can't be less than IB_WQS_RESET.
v0: https://lore.kernel.org/lkml/932f87b48c07278730c3c760b3a707d6a984b524.1621332736.git.leonro@xxxxxxxxxx
