cosmetic: rename function .._conn_reset() to .._conn_init()

We do allocate connections dynamically and we initialize them
once by calling mgcp_rtp_conn_reset(). Calling this a reset
function implies that the reset happens multiple times while
the struct lives. This is not tha case, so lets change the
suffix to _init()

- rename mgcp_rtp_conn_reset() to mgcp_rtp_conn_init()
