[PATCH] don't call regfree() on uninitialized regex_t

[Wayne Davison <wayned@xxxxxxxxxxxxxxxxxxxxx>]

While I was fixing a few compiler warnings in zcond_regex_match(), I
noticed that regfree() could be called on an uninitialized regex_t if
the "id" value passed in to the function was invalid.  Attached is one
possible fix.
