Well, since kauth_cred_t can be extended, I foresee no need to change
VFS design. one additionnal credential is required here, struct file *,
we can just optionaly add it up like I did in this patch.

There is a possible exception: VOP_FALLOCATE touches file content, and
it does not pass kauth_cred_t. Obviously this was forgotten when the VOP
was created.
