mpt2sas: Avoid type casting for direct I/O commands
A type casting error caused the max volume LBA to be truncated from 64
to 32 bits. The virtual LBA would also get truncated to 32 bits in the
case of a 16-byte READ/WRITE command.
Rewrite entire function to get rid of code duplication and type casts.
Use get/put_unaligned wrappers to extract and replace the LBA field in
the MPI request CDB.
