  gost_ec_keyx: Fix CID 253282 Dereference null return value

`param' is used unconditionally in pkey_GOST_ECcp_encrypt() so we can
unconditionally check (vs in any particular `if' branch) for it's being
non-NULL. This is similar to how pkey_GOST_ECcp_decrypt() works with
`param'.

Closes #174.

  gost_ec_keyx: Remove redundant code

This `if' statement is redundant since ce40d60 ("Bugfix.")

get_gost_engine_param() have no side effects and `param' is set to
`gost_cipher_list' only if already equal to `gost_cipher_list'.
