qcacld-2.0: Clear MC filters when more than max available
When number of link MC addresses configured are more than the
maximum firmware MC address list size, host sets the firmware's
MC filters up to the max and skipping the rest. As a result
firmware drops the MC packets for the addresses whose MC filter
is not set.
To fix this clear the firmware MC filters when the number of kernel
MC addresses list is greater than the firmware's MC filter list size.
When no filters are configured firmware allows all the MC frames
to the host.
