Subject: [PATCH] GFS2: fix code parameter error in inode_go_lock

In inode_go_lock() function, the parameter order of list_add() is error.
According to the define of list_add(), the first parameter is new entry
and the second is the list head, so ip->i_trunc_list should be the
first parameter and the sdp->sd_trunc_list should be second.
