pciexp_device: Join pciexp_find_(next_)extended_cap() APIs

Browse Source 
Move the `offset` parameter into pciexp_find_extended_cap(). If it's
called with `0`, we start a new search. If it's an existing offset,
we continue the search.

This makes it easier to search for multiple occurences of a capa-
bility in a single loop.
