net: intel: igc_ptp: fix build for UML
On a UML build, the igc_ptp driver uses CONFIG_X86_TSC for timestamp
conversion. The function that is used is not available on UML builds,
so have the function use the default system_counterval_t timestamp
instead for UML builds.
Prevents this build error on UML:
../drivers/net/ethernet/intel/igc/igc_ptp.c: In function ‘igc_device_tstamp_to_system’:
../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: implicit declaration of function ‘convert_art_ns_to_tsc’ [-Werror=implicit-function-declaration]
return convert_art_ns_to_tsc(tstamp);
../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: incompatible types when returning type ‘int’ but ‘struct system_counterval_t’ was expected
return convert_art_ns_to_tsc(tstamp);
Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver")
