qcacld-3.0: Calculate LI per AP's BI and DTIM
Propagation from qcacld-2.0 to qcacld-3.0.
Assuming gEnableModulatedDTIM=9 and gMaxLIModulatedDTIM=9,
when AP's beacon interval is 100ms, the DUT's listen
interval is 900ms, it is OK; But if AP's beacon interval
is 200ms or more, the DUT's listen interval is 1800ms
or even more. This causes large data latency.
