fs: dlm: don't set stop rx flag after node reset
commit 15c63db8e86a72e0d5cfb9bf0cd1870e39a3e5fe upstream. Similar to the stop tx flag, the rx flag should warn about a dlm message being received at DLM_FIN state change, when we are assuming no other dlm application messages. If we receive a FIN message and we are in the state DLM_FIN_WAIT2 we call midcomms_node_reset() which puts the midcomms node into DLM_CLOSED state. Afterwards we should not set the DLM_NODE_FLAG_STOP_RX flag any more. This patch changes the setting DLM_NODE_FLAG_STOP_RX in those state changes when we receive a FIN message and we assume there will be no other dlm application messages received until we hit DLM_CLOSED state.
