LU-10672 lnet: pass in only time64_t to lnet_notify

With the migration to 64 bit second time some calls to lnet_notify
did not get updated to use time64_t. Update those calling points.
Also for the ioctl IOC_LIBCFS_NOTIFY_ROUTER we pass in the number
of seconds since the epoch. We subtract the current epoch time but
we missed adding in the current number of seconds since booting
since the lnet ping code expects the seconds since boot to be used.
