Jason A. Donenfeld 639c07b47c random: schedule jitter credit for next jiffy, not in two jiffies
[ Upstream commit 1227334713 ]

Counterintuitively, mod_timer(..., jiffies + 1) will cause the timer to
fire not in the next jiffy, but in two jiffies. The way to cause
the timer to fire in the next jiffy is with mod_timer(..., jiffies).
Doing so then lets us bump the upper bound back up again.

Fixes: 50ee7529ec ("random: try to actively add entropy rather than passively wait for it")
Fixes: 829d680e82 ("random: cap jitter samples per bit to factor of HZ")
