[mod_event_multicast] Fix memory leak

Add support for the Elbrus architecture

Related to FS-11309.

Commit bc3e1c9e introduced a typo that
results in EL_REFRESH never being used, even if available. This can
cause the screen to garble.

This fixes the typo.

Taken from FS-11193:

In "event_handler()" function, when encrypting data using openssl 1.1.0,
the context ctx is allocated by "EVP_CIPHER_CTX_new()", then data is
encrypted, and at the end, EVP_CIPHER_CTX_cleanup is called. This
function resets the context (the function itself is deprecated, and has
been renamed to "EVP_CIPHER_CTX_reset) so that it can be used again. The
correct call would be to "EVP_CIPHER_CTX_free()", which frees the
memory. The code for openssl 1.0 is OK, since the "ctx" struct is kept
in stack.  The same thing happens during decryption. "ctx" is allocated,
but never freed.
