openssl: use RB_GC_GUARD instead of volatile
From doc/extension.rdoc:
>
> Using the RB_GC_GUARD macro is preferable to using the "volatile"
> keyword in C. RB_GC_GUARD has the following advantages:
>
> 1) the intent of the macro use is clear
>
> 2) RB_GC_GUARD only affects its call site, "volatile" generates some
> extra code every time the variable is used, hurting optimization.
>
> 3) "volatile" implementations may be buggy/inconsistent in some
> compilers and architectures. RB_GC_GUARD is customizable for broken
> systems/compilers without those without negatively affecting other
> systems.
* ext/openssl/ossl_asn1.c (ossl_asn1_traverse, ossl_asn1_decode,
ossl_asn1_decode_all): use RB_GC_GUARD instead of volatile
