UBUNTU: SAUCE: bcache: prevent crash on changing writeback_running

BugLink: http://bugs.launchpad.net/bugs/1357295

commit a664d0f05a2ec02c8f042db536d84d15d6e19e81
    bcache: fix crash on shutdown in passthrough mode

added a safeguard in the shutdown case. At least while not being
attached it is also possible to trigger a kernel bug by writing into
writeback_running. This change adds the same check before trying to
wake up the thread for that case.

bcache: fix uninterruptible sleep in writeback thread

BugLink: http://bugs.launchpad.net/bugs/1357295

There were two issues here:

- writeback thread did not start until the device first became dirty
- writeback thread used uninterruptible sleep once running

Without this patch I see kernel warnings printed and a load average of
1.52 after booting my test VM. With this patch the warnings are gone and
the load average is near 0.00 as expected.

We never started the writeback thread in this case, so don't stop it.
