btrfs: add a btrfs_inode pointer to struct btrfs_bio
All btrfs_bio I/Os are associated with an inode. Add a pointer to that
inode, which will allow to simplify a lot of calling conventions, and
which will be needed in the I/O completion path in the future.
This grow the btrfs_bio structure by a pointer, but that grows will
be offset by the removal of the device pointer soon.
