wm97xx_battery: Use DEFINE_MUTEX() for work_lock
work_lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). This patch also removes an unused bat_lock mutex. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
