fs: dlm: relax sending to allow receiving
This patch drops additionally the sock_mutex when there is a sending
message burst. Since we have acknowledge handling we free sending
buffers only when we receive an ack back, but if we are stuck in
send_to_sock() looping because dlm sends a lot of messages and we never
leave the loop the sending buffer fill up very quickly. We can't receive
during this iteration because the sock_mutex is held. This patch will
unlock the sock_mutex so it should be possible to receive messages when
a burst of sending messages happens. This will allow to free up memory
because acks which are already received can be processed.
