random: always update the entropy pool under the spinlock Instead of using lockless techniques introduced in commit 902c098a3663, use spin_trylock to try to grab entropy pool's lock. If we can't get the lock, then just try again on the next interrupt. Based on discussions with George Spelvin. Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: George Spelvin <linux@horizon.com>
