fs: remove the inode argument to ->d_real() method
The only remaining user of ->d_real() method is d_real_inode(), which
passed NULL inode argument to get the real data dentry.
There are no longer any users that call ->d_real() with a non-NULL
inode argument for getting a detry from a specific underlying layer.
Remove the inode argument of the method and replace it with an integer
'type' argument, to allow callers to request the real metadata dentry
instead of the real data dentry.
All the current users of d_real_inode() (e.g. uprobe) continue to get
the real data inode. Caller that need to get the real metadata inode
(e.g. IMA/EVM) can use d_inode(d_real(dentry, D_REAL_METADATA)).
