The hashtable is guaranteed to only contain font faces which are
currently referenced, hence there is no need to remove any font face
when it is reset (just like for toy-font).
This makes the function simpler and fixes the assertion
Assertion failed: predicate != NULL, file cairo-hash.c, line 373
hit by multiple tests (the first one being "clear").

Similar to the freetype and toy font backends, use a hash table
to map logfont,hfont to font faces.
This fixes the multiple embedding of the same font in PDF.
