apphandler: Fix for total session slots count

Issue: Get session info shows 60 sessions as total number of sessions
       for all medium_type as lan-802 channels instead actual sessions.

Fix: Initialize the channel Info structure to empty to avoid wrong
     calculation of total number of session slots for all channels
     which are having medium_type as lan-802.

Tested:
Verified using ipmitool command.
Before:
Command: ipmitool -I lanplus -H <BMC-IP> -C 17 -U root -P <Password> session info all
Response:
session handle                : 129
slot count                    : 60
active sessions               : 1
user id                       : 1
privilege level               : ADMINISTRATOR
session type                  : IPMIv2/RMCP+
channel number                : 0x03
console ip                    : 10.190.201.113
console mac                   : 00:00:00:00:00:00
console port                  : 42963

After:
Command: ipmitool -I lanplus -H <BMC-IP> -C 17 -U root -P <Password> session info all
Response:
session handle                : 129
slot count                    : 30
active sessions               : 1
user id                       : 1
privilege level               : ADMINISTRATOR
session type                  : IPMIv2/RMCP+
channel number                : 0x03
console ip                    : 10.190.201.113
console mac                   : 00:00:00:00:00:00
console port                  : 48994
