net: ethtool: reject an out of range hwtstamp provider index
A provider index of 0xFFFFFFFF picks a provider on hardware that has
none. phc_index is an int where -1 means no PHC, and the u32 from user
space ends up as -1, so the two match.
TSINFO_GET uses -1 for "no provider requested" and answers with the
default provider instead of an error.
Reject the value in the netlink policy, which covers every comparison
site.
