fs: dlm: revert check required context while close
This patch reverts commit 2c3fa6ae4d52 ("dlm: check required context while close"). The function dlm_midcomms_close(), which will call later dlm_lowcomms_close(), is called when the cluster manager tells the node got fenced which means on midcomms/lowcomms layer to disconnect the node from the cluster communication. The node can rejoin the cluster later. This patch was ensuring no new message were able to be triggered when we are in the close() function context. This was done by checking if the lockspace has been stopped. However there is a missing check that we only need to check specific lockspaces where the fenced node is member of. This is currently complicated because there is no way to easily check if a node is part of a specific lockspace without stopping the recovery. For now we just revert this commit as it is just a check to finding possible leaks of stopping lockspaces before close() is called.
