[PATCH] scsi: Remove usage of struct timeval

[Tina Ruchandani <ruchandani.tina@gmail.com>]

struct timeval will have its tv_sec field overflow on 32-bit systems
in year 2038 and beyond. This patch removes the usage of struct timeval
and instead uses 64-bit ktime_t to get the current milliseconds
to populate pmcraid_timestamp_data.
