    equix: avoid a coverity warning in hashx_alloc()
    
    This addresses one of the warnings in issue #40792. As far as I can tell
    this is a false positive, since the use of "ctx->type" in hashx_free()
    can only be hit after the unioned code/program pointer is non-NULL. It's
    no big deal to zero this value explicitly to silence the warning though.
