[RESEND][PATCH] Fix add_timer_randomness throttling

[Torsten Duwe]

[now with "PATCH" tag]

It looks to me that commit a283b5c459784f97 has one replacement too much:
in add_timer_randomness, entropy_count is compared to trickle_thresh,
which are _both_ scaled up by ENTROPY_SHIFT. I'd therefore revert that hunk.
