Jason A. Donenfeld 45102b538a random: wake up /dev/random writers after zap ...

[ Upstream commit 042e293e16e3aa9794ce60c29f5b7b0c8170f933 ]

When account() is called, and the amount of entropy dips below
random_write_wakeup_bits, we wake up the random writers, so that they
can write some more in. However, the RNDZAPENTCNT/RNDCLEARPOOL ioctl
sets the entropy count to zero -- a potential reduction just like
account() -- but does not unblock writers. This commit adds the missing
logic to that ioctl to unblock waiting writers.
