msm: lmh_lite: re-enable lmh interrupt only during polling



There is a possibility that lmh driver will receive interrupts for
back to back short lived hardware throttling condition. Re-enable
interrupt only in polling mode handler to mitigate the impact of
these zero intensity reporting hw throttling conditions.
