[PATCH 1/3] lightnvm: pblk: delete writer kick timer before stopping thread

[hans.ml.holmberg@owltronix.com]

From: Hans Holmberg <hans.holmberg@cnexlabs.com>

Unless we delete the timer that wakes up the write thread
before we stop the thread we risk re-starting the thread, so
delete the timer first.
