Fix IPMI response message for Asset tag

Changes:
     The response is:
     'Unable to send RAW command (channel=0x0 netfn=0x2c
     lun=0x0 cmd=0x8 rsp=0xc9): Parameter out of range: 1 != 0'
     which comes from ipmitool .

The ipmitool source code for this message can be viewed at
lib/ipmi_raw.c line 390

The testcase expects this message and tries to match the rsp=0xc9):
Parameter out of range: part.
But it fails because it erroneously expects  resp  -- whereas ipmitool
will always print  rsp  here.

So, the Should contain keyword will fail on this typo for any box, any vendor.

Tested:
   - NA
