bcachefs: Ensure buckets have io_time[READ] set
It's an error if a bucket is in state BCH_DATA_cached but not on the LRU btree - i.e io_time[READ] == 0 - so, make sure it's set before adding it. Also, make some of the LRU code a bit clearer and more direct. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
