[GFS2] Fix a couple of refcount leaks.
recovery.c add a brelse to deal with gfs2_replay_read_block being called twice on the same block. add a dput to drop the ref count on the root inode. This was causing lingering glocks and thus causing a mount failure to hang. Fix a endian conversion macro that was was swizzling 16bits when it should have been swizzling 32.
