Subject: [PATCH 276/279] libglusterfs: write error handling when filesystem have no space left

This is a backport of: http://review.gluster.org/#/c/11029/

When no space left on filesystem and user want to perform any operation
which result to change in /var/lib/glusterd/* files then glusterd is
failing to write on temporary file.

Fix is to handle error when write failed on temporary files due to no
space left on file system.
