outdated documentation for connection_handle_write_impl()

 * This function gets called either from conn_write_callback() in main.c
 * when libevent tells us that conn wants to write, or below
 * from connection_buf_add() when an entire TLS record is ready.

, or below ... when an entire TLS record is ready hasn't been accurate since d9746bd468f551d1ada57d962b20eddd15256ce9.

It and connection_handle_read_impl also don't mention only ever being called indirectly via connection_handle_write()/read since d3be00e0f454998db6387c8547d218a0db93db21, but that's more readily apparent at least.
