storagecommands: Fix for GetFruAreaInfo command

Issue: GetFruAreaInfo command is giving incorrect response for Invalid
FRU Device ID's.

Fix: Add check for invalid FRU Device ID's to return completion code as
0xCB.

Tested:
Verified using ipmitool raw commands.
Case 1: Valid FRU Device ID:
Command:  ipmitool raw 0x0a 0x10 0xce //Get fru Area info
Response: a9 00 00
Case 2: Invalid FRU Device ID:
Command:  ipmitool raw 0x0a 0x10 0x01 //Get fru Area info
Response: Unable to send RAW command (channel=0x0 netfn=0xa lun=0x0
          cmd=0x10 rsp=0xcb): Requested sensor, data, or record not
          found
