[SCSI] bnx2i: Fixed packet error created when the sq_size is set to 16
The number of chip's internal command cell, which is use to generate SCSI cmd packets to the target, was not initialized correctly by the driver when the sq_size is changed from the default 128. This, in turn, will create a problem where the chip's transmit pipe will erroneously reuse an old command cell that is no longer valid. The fix is to correctly initialize the chip's command cell upon setup.
