btrfs: directly pass the inode to btrfs_is_data_extent_shared()
Currently we pass a root and an inode number as arguments for
btrfs_is_data_extent_shared() and the inode number is always from an
inode that belongs to that root (it wouldn't make sense otherwise).
In every context that we call btrfs_is_data_extent_shared() (fiemap only),
we have an inode available, so directly pass the inode to the function
instead of a root and inode number. This reduces the number of parameters
and it makes the function's signature conform to most other functions we
have.
