Previously, this was done with a simple check in the shrinker - "if btree node is in range being pinned, don't free it" - but this generated OOMs, as our shrinker wasn't well behaved if there was less memory available than expected. Instead, we now have two different shrinkers and lru lists; the second shrinker being for pinned nodes, with seeks set much higher than normal - so they can still be freed if necessary, but we'll prefer not to.

For example, `cat /sys/fs/bcachefs/*/internal/rebalance_status` would return invalid data in the `duration waited` field because dividing by the number of nanoseconds in a minute requires the divisor parameter to be u64.
