ext4: Don't use 'struct dentry' for internal lookups
This is a port of a patch from Linus which fixes a 200+ byte stack
usage problem in ext4_get_parent().
It's more efficient to pass down only the actual parts of the dentry
that matter: the parent inode and the name, instead of allocating a
struct dentry on the stack.
