Add support in the driver to check for valid response info in the scsi
state, then check to see if the response code is
MPI2_SCSITASKMGMT_RSP_INVALID_FRAME; when this condition occurrs, the driver
will return DID_SOFT_ERROR.  A return code of DID_SOFT_ERROR will result in
a retry at the scsi-mid layer level.  An additional change added to obtain
the response code from the 1st byte of the response info instead of last.
