preproc: Fix the macro-parameter check for conditional code

Browse Source 
Mistreating the macro-parameter, just equivalent to the given
argument number, leads to casting an unnecessary error. Fix to
assemble the conditional code correctly.

Fixes: de7acc3a46 ("preproc: defer %00, %? and %??
expansion for nested macros, cleanups")
