PATCH 1/11 mpt2sas: Corrected time stamp

incorrect timestamp on 32 bit platforms: The upper 32 bit of
the timestamp was getting truncated when converting seconds to milliseconds, which was due to the variable being long. To fix the problem, the variable needs to be u64. Also the microseconds conversion to milliseconds was incorrect; it should be divide by 1000 instead of divide by 8.
