btrfs: Make get_extent_t take btrfs_inode
In addition to changing the signature, this patch also switches all the functions which are used as an argument to also take btrfs_inode. Namely those are: btrfs_get_extent and btrfs_get_extent_filemap. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
