qapi: Drop unused c_null()

Now that we are always bulk-initializing a QAPI C struct to 0
(whether by g_malloc0() or by 'Type arg = {0};'), we no longer
have any clients of c_null() in the generator for per-element
initialization.  This patch is easy enough to revert if we find
a use in the future, but in the present, get rid of the dead code.
