 Description   

mongoc_counter_protocol_ingress_error_inc is called in mongoc_cluster_try_recv to update the shared memory counters when there is an error reading from the application connection.

mongoc_cluster_run_command_opquery and mongoc_cluster_run_opmsg do not call this. And the single and multi-threaded monitoring code does not call it either.

For deduplicating the network error logic on application connections, it may be good to add an argument to _handle_network_error to indicate whether it is a read or write error, and if it is a read error, call mongoc_counter_protocol_ingress_error_inc.

Though monitoring connections will likely need to call this separately.
