fuse: send lookup if inode_ctx is not set
During resolving of an entry or inode, if inode ctx was not set, we will send a lookup. This patch also make sure that inode_ctx will be created after every inode_link Change-Id: I4211533ca96a51b89d9f010fc57133470e52dc11 BUG: 1297311 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> Reviewed-on: http://review.gluster.org/13225 Reviewed-by: Dan Lambright <dlambrig@redhat.com> Tested-by: Dan Lambright <dlambrig@redhat.com>
