[PATCH] clocksource: Use correct limit for wd-cs-wd read back delay in printing

[Aaron Lu <ziqianlu@bytedance.com>]

With commit 4ac1dd3245b9("clocksource: Set cs_watchdog_read() checks
based on .uncertainty_margin"), the limit for wd-cs-wd read back delay
is changed from the static WATCHDOG_MAX_SKEW to dynamic ones based on
watchdog and cs' uncertainty_margin, but WATCHDOG_MAX_SKEW is still used
when dumping information.

Fix this by using the actual limit: md(2 * watchdog->uncertainty_margin)
+ cs->unvertainty_margin.
