This fix correctly releases allocated resources in case of error.

Description of problem: When the setxattr fails for some extended attributes, fuse leaks memory. This can happen if you try to set 'system.posix_acl_access' but gluster doesn't have acl's enabled. Version-Release number of selected component (if applicable): mainline How reproducible: Always Steps to Reproduce: 1. gluster volume create test server:/brick 2. mount -t glusterfs server:/test /test 3. touch /test/file 4. for i in {1..100000}; do setfattr -n system.posix_acl_access -v "1" /test/file; done Actual results: Doing a state dump, a leak of fuse_state_t structures is seen. Expected results: No leak should happen. Additional info: It seems that the state is not released after having been allocated if a pre-op check fails.
