    [GFS2] Remove unneeded i_spin
    
    This patch removes a vestigial variable "i_spin" from the gfs2_inode
    structure.  This not only saves us memory (>300000 of these in memory
    for the oom test) it also saves us time because we don't have to
    spend time initializing it (i.e. slightly better performance).
