bn: keep reference to temporary OpenSSL::BN object created by GetBNPtr()
GetBNPtr() accepts both OpenSSL::BN and Ruby integers. In the latter
case, it creates a temporary OpenSSL::BN internally. The OpenSSL::BN
object immediately disappears from the stack and is not protected from
GC.
Fixes: https://github.com/ruby/openssl/issues/87
