Filter: Delete SEL not supported through filter

Issue: Doing SEL reserve and issuing IPMI Delete SEL,
       returns 0xcb instead of 0xc1

Fix: fixed by returning proper error code as invalid command (0xc1)

Tested:
verified with ipmitool raw commands

Command : ipmitool raw 0x0a 0x42 //reserve Sel
Response: 05 00

Command : ipmitool raw 0x0a 0x46 0x05 0x00 0xff 0xff // delete Sel
Response: Unable to send RAW command (channel=0x0 netfn=0xa lun=0x0
          cmd=0x46 rsp=0xc1): Invalid command
