Convert a fragmented extended attr to a VP.

Format is:

attr length extended-attr flag data...

But for the first fragment, we get passed a pointer to the "extended-attr"

	)

Create any kind of VP from the attribute contents.

"length" is AT LEAST the length of this attribute, as we expect the caller to have verified the data with fr_radius_ok(). "length" may be up to the length of the packet.

Returns

Length on success.
-1 on failure.
