USB: usbmon: mask seconds properly in text API
The code does not implement the comment, so timestamps for long traces become confusing instead of wrapping neatly as expected. This was actually observed. Fortunately for API being in debugfs, we can just fix this instead of staying bug-for-bug compatible. Double fortunately, the stable binary API is not affected.
