    fuse: fix memory leak in fuse_getxattr()
    
    The fuse_getxattr() function was not freeing fuse_state_t resulting in a
    memory leak. As a result, when continuous writes (run dd command in a loop)
    were done from a FUSE mount point, the OOM killer killed the client
    process (glusterfs).
