scsi: scsi_transport_fc: use 64-bit timestamps consistently

The get_seconds() helper returns an 'unsigned long' value, which can
overflow on 32-bit architectures. Since the interface we pass it into
already uses a 64-bit type, we can just use ktime_get_real_seconds()
instead.

While we generally prefer local timestamps in CLOCK_MONOTONIC format
(ktime_get_seconds), this keeps using the CLOCK_REALTIME version in order
to maintain compatibility with existing code.
