Set the current interface number based on the channel name

Now that netipmid is launched with -c <channel_name>, it is possible
to look up the channel number for the 'current channel' 0x0e for
commands that get handled for session init/fini. This is needed for
tools that request channel access info for the current channel.

Tested-by: run ipmitool to establish a session, using -vvvvv
           see that the get channel auth command returns the correct
           channel ID.

	   In this config, eth0 is channel 3 and eth1 is channel 1.

           As is evident by the highlighted <0X> byte in each of the
           returned responses, the value of the current channel byte
           went from a hard-coded value 03 to a value that changed with
           the current channel.

	   Before:
           ipmitool -H <ip of eth0> ... mc info
           ...
           >> sending packet (23 bytes)
            06 00 ff 07 00 00 00 00 00 00 00 00 00 09 20 18
            c8 81 00 38 0e 04 35
           << received packet (31 bytes)
            06 00 ff 07 00 00 00 00 00 00 00 00 00 10 81 1c
