char: remove socket_try_connect method

Browse source 
The qemu_chr_open_socket_fd() method multiplexes three different
actions into one method. The socket_try_connect() method is one
of its callers, but it only ever want one specific action
performed. By inlining that action into socket_try_connect()
we see that there is not in fact any failure scenario, so there
is not even any reason for socket_try_connect to exist. Just
inline the asynchronous connection attempts directly at the
places that need them. This shortens & clarifies the code.
