This reverts commit 6268dc2c4703aabfb0b35681be709acf4c2826c6.

This patch depends on commit c4dc2497d50d ("bcache: fix high CPU
occupancy during journal") which is reverted in previous patch. So
revert this one too.

Fixes: 6268dc2c4703 ("bcache: free heap cache_set->flush_btree in bch_journal_free")
