bcache: remove retry_flush_write from struct cache_set

Browse Source 
In struct cache_set, retry_flush_write is added for commit c4dc2497d5
("bcache: fix high CPU occupancy during journal") which is reverted in
previous patch.

Now it is useless anymore, and this patch removes it from bcache code.
