[SCSI] mpt2sas: mpt2sas_base_get_sense_buffer_dma should be returning little endian
cpu_to_le64 when calculating the physical dma address. This will properly
handle endianess on big endian systems. The return value of this function
was changed from dma_addr_t to __le64. Remove the typecasting of u32 when
setting the SenseBufferLowAddress, since its already in __le32 format.
