Issue:
Linux Implementation(pcap-linux.c): The iface_get_ts_types function silently ignoring ENODEV errors during interface timestamp capability checking, allowing permission errors to bereported later during socket operations

Fixes:
return PCAP_ERROR_NO_SUCH_DEVICE when encountering ENODEV, instead of ignoring the error
