Btrfs: Fix super block updates during transaction commit
The super block written during commit was not consistent with the state of

btrfs: Code cleanup
Attaching below is some of the code cleanups that i came across while
reading the code.
a) alloc_path already calls init_path.
b) Mention that btrfs_inode is the in memory copy.Ext4 have ext4_inode_info as
