UFS error handling now is doing more than just re-probing, but also

from being disturbed by error handling, move the host_sem from wl pm
ops
to ufshcd_suspend_prepare() and ufshcd_resume_complete().
If lock_system_sleep() and unlock_system_sleep() would be used in the
error handler, would that allow to remove host_sem?
Please kindly check my reply in patch #5.
Thanks,
Can Guo.
