Some clients attempt to invoke streamoff & driver fd close
(msm_vidc_close) sequence concurrently. So there might be chances
some commands willbe posted to command queue even after closing
hfi session(HFI_CMD_CLOSE) completed. So due to invalid session_id
firmware asserts.
Added change to avoid above mentioned issue and also amended minor
logging changes.
