ec: Special handling of anonymous fd

Anonymous file descriptors need to be handled specially because
they can be used in some non standard ways (i.e. an anonymous fd
can be used without having been opened).

This caused NFS to fail on some operations because ec always
expected to have a previous successful opendir call (from patch
http://review.gluster.org/9098/).

This patch treats all anonymous fd as opened on all subvolumes.
