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.
