    GFS2: Fix unclaimed_blocks() wrapping bug and clean up · c743ffd0

    When rgd->rd_free_clone is less than rgd->rd_reserved, the
    unclaimed_blocks() calculation would wrap and produce
    incorrect results. This patch checks for this condition
    when this function is called from gfs2_mblk_search()
    
    In addition, the use of this particular function in other
    places in the code has been dropped by means of a general
    clean up of gfs2_inplace_reserve(). This function is now
    much easier to follow.
    
    Also the setting of the rgd->rd_last_alloc field is corrected.
