[SCSI] mptlan: bug fix, only half the message frame is dma'd resulting in corruption
NB = number of blocks. This represents the number of blocks to
transfer. The block size is based on the message frame size provided
in the ioc_facts. A value of zero indicates the entire message frame
should be copied. This is two bit value. So by setting this to
non-zero vaule, you increase performance by reducing amount of data
needing to be dma'd. The value that is stored in ioc->ReqeustNB is
sometimes a non-zero vaule, which creates a bug in mptlan, where not
the entire message frame is getting transfer to firware, resulting in
corruption. This fix sets the default to zero, thus entire message
frame is copied.
