[GFS2] Clean up gfs2_trans_add_revoke()
The following alters gfs2_trans_add_revoke() to take a struct gfs2_bufdata as an argument. This eliminates the memory allocation which was previously required by making use of the already existing struct gfs2_bufdata. It makes some sanity checks to ensure that the gfs2_bufdata has been removed from all the lists before its recycled as a revoke structure. This saves one memory allocation and one free per revoke structure. Also as a result, and to simplify the locking, since there is no longer any blocking code in gfs2_trans_add_revoke() we must hold the log lock whenever this function is called. This reduces the amount of times we take and unlock the log lock. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
