clocksource: Handle negative skews in "skew is too large" messages

Browse source

[ Upstream commit e40806e9bc ]

The nanosecond-to-millisecond skew computation uses unsigned arithmetic,
which produces user-unfriendly large positive numbers for negative skews.
Therefore, use signed arithmetic for this computation in order to preserve
the negativity.
