Kyoungrul Kim 8d1af5c6af scsi: ufs: core: Check LSDBS cap when !mcq ...

[ Upstream commit 0c60eb0cc320fffbb8b10329d276af14f6f5e6bf ]

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB
mode unconditionally even when the LSDBS of device HCI cap is 1. This makes
commands time out and causes device probing to fail.

To prevent that problem, check the LSDBS cap when MCQ is not supported.
