[PATCH v1 2/2] ufs: core: force reset after mcq abort all

[peter.wang at mediatek.com]

From: Peter Wang <peter.wang at mediatek.com>

In mcq mode gerneal case, cq (head/tail) poniter is same as
sq pointer (head/tail) if the hwq is empty.

But if command send to device and abort it,
no response return and cq point will less than sq.
In this case will have unpredictable error.
This patch force reset for this case.

Below is error log
[   34.976612][    C3] ufshcd-mtk 112b0000.ufshci: OCS error from controller = 3 for tag 19
