Add self channel number conversion function

Support for self channel number conversion added. This will
be used by IPMI commands like GetUserAccess, GetChannelInfo etc.
to query the details for the channel in which the command is
requested. Self channel number 0xE will be converted to proper
channel number by this function

Unit-Test:
Performed that commands received through ipmid channel are marked
as channel 0xF and through netipmid as 0x1, when channel number
0xE is used
