net: fec: ptp: remove unused variable 'ns' in fec_time_keep()
Fixes the following W=1 kernel build warning(s):
drivers/net/ethernet/freescale/fec_ptp.c:523:6: warning:
variable 'ns' set but not used [-Wunused-but-set-variable]
523 | u64 ns;
| ^~
After commit 6605b730c061 ("FEC: Add time stamping code and a PTP
hardware clock"), variable 'ns' is never used in fec_time_keep(),
so removing it to avoid build warning.
