Fix regression in Type1 Fallback

As a result of the changes to improve the status checking,
_cairo_type2_charstrings_init() was failing due to the failure
status returned when the font->output stream is destroyed.
This is because _cairo_type2_charstrings_init() does not
create an output stream.

Fix this by initializing font->output to NULL and only
destroy it if not NULL.
