bcache: Revert "bcache: fix high CPU occupancy during journal"
commit 249a5f6da57c28a903c75d81505d58ec8c10030d upstream.
This reverts commit c4dc2497d50d9c6fb16aa0d07b6a14f3b2adb1e0.
This patch enlarges a race between normal btree flush code path and
flush_btree_write(), which causes deadlock when journal space is
exhausted. Reverts this patch makes the race window from 128 btree
nodes to only 1 btree nodes.
