Kernel: Use m_inode to stat in FileDescription::stat() if available

Browse source 
This is necessary since the Device class does not hold a reference to
its inode (because there could be multiple), and thus doesn't override
File::stat(). For simplicity, we should just always stat via the inode
if there is one, since that shouldn't ever be the wrong thing.

This partially reverts #7867.
