[ Upstream commit be32acff43800c87dc5c707f5d47cc607b76b653 ]
Urgent bkops level is used to compare against actual bkops status read from UFS device. Urgent bkops level is set during initialization and might be updated in exception event handler during runtime. But it should not be updated to the actual bkops status every time when auto bkops is toggled. Otherwise, if urgent bkops level is updated to 0, auto bkops shall always be kept enabled.
