    storage/posix: Execute syscalls in xattrop under different locks

    ... and not inode->lock. This is to prevent the epoll thread from
    *potentially* being blocked on this lock in the worst case for
    extended period elsewhere in the brick stack, while the syscalls
    in xattrop are being performed under the same lock by a different
    thread. This could potentially lead to ping-timeout, if the only
    available epoll thread is busy waiting on the inode->lock, thereby
    preventing it from picking up the ping request from the client(s).

    Also removed some unused functions.
