Fix: refactor get channel cipher suite command

Get channel cipher suites command updated as per new ipmi structure.

Tested:
ipmitool raw 0x06 0x54 0x01 0x00 0x80
01 c0 03 01 41 81 c0 11 03 44 81                //response

Also verified by issuing cmd:
ipmitool channel getciphers ipmi 0x01
which listed supported CIA algorithms as response
