David Sterba 70f49f7b9a btrfs: add helper to get fs_info from struct inode pointer ...

[ Upstream commit 41044b41ad ]

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.
