rfnoc: Enable drop counter on chdr_ctrl_endpoint
This class has a member _num_drops, which can be read out using the
get_num_drops() API call. However, when dropping packets, this counter
was not incremented, which is fixed now.
This also includes a very minor optimization from 2 map<> lookups to
1 lookup (they are in O(log N)). Since there are usually a small
two-digit number of endpoints connected to the async message receiver,
this change is not expected to yield major improvements, but the lookup
*is* in a hot loop.
