mpi3mr: Divert WriteSame IOs which has unmap and ndob bit set to firmware if its transfer length exceeds firmware limit.

[chandrakanth.patil_broadcom.com]

Summary

Firmware advertise the transfer lenght for writesame commands to driver during init.
So for any writesame IOs with ndob and unmap bit set and transfer lengh is greater
than the max write same length specified by the firmware, then direct those commands
to firmware instead of hardware othewise hardware will break.

I don't understand this change. Can you explain why it is needed? It seems unrelated.

I have used it for get_unaligned_be32() API which is defined in <asm/unaligned.h> header file available in the linuxkpi.
debug flag -g is used for debug symbols.
