    afr: perform replace-brick in a synctask

    Problem:
    replace-brick setxattr is not performed inside a synctask. This can lead
    to hangs if the setxattr is executed by epoll thread, as the epoll
    thread will be waiting for replies to come where as epoll thread is the
    thread that needs to epoll_ctl for reading from socket and listen.

    Fix:
    Move replace-brick to synctask to prevent epoll thread hang.

    This patch is in line with the fix performed in
    http://review.gluster.org/#/c/12163/
