Use BN_GENCB_get_arg
The
BN_GENCBstructure is opaque in OpenSSL 3.x, meaning direct member access (ctx->arg) is not allowed and causes compilation failures.This PR replaces direct struct member access with the
BN_GENCB_get_arg()accessor function, which is the proper API for retrieving the callback argument in OpenSSL 1.1.0+.The existing code had a TODO comment acknowledging this, with the correct API call commented out. This change simply uses the accessor as intended.
