[PATCH net-next v17 05/14] net: net_tstamp: Add unspec field to hwtstamp_source enumeration

[Kory Maincent]

Prepare for future support of saving hwtstamp source in PTP xarray by
introducing HWTSTAMP_SOURCE_UNSPEC to hwtstamp_source enum, setting it
to 0 to match old behavior of no source defined.
