btrfs: add helper to get fs_info from struct inode pointer
Add a convenience helper to get a fs_info from a VFS inode pointer instead of open coding the chain or using btrfs_sb() that in some cases does one more pointer hop. This is implemented as a macro (still with type checking) so we don't need full definitions of struct btrfs_inode, btrfs_root or btrfs_fs_info.
