[PATCH 2/2] Make the new mime-surface-api succeed

[Uli Schlachter]

When removing mime data, _cairo_user_data_array_set_data () is called with a
NULL argument. This leaves behind an entry with key == NULL in the user data
array. Skip those entries instead of dereferencing NULL.

(The NULL entry in the array let's us avoid moving data around and/or doing a
memory allocation later, so I guess it might be a good idea to keep that)
