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.
