power: supply: core: Remove might_sleep() from power_supply_put()

[ Upstream commit f6da4553ff24a5d1c959c9627c965323adc3d307 ]

The put_device() call in power_supply_put() may call
power_supply_dev_release(). The latter function does not sleep so
power_supply_put() doesn't sleep either. Hence, remove the might_sleep()
call from power_supply_put(). This patch suppresses false positive
complaints about calling a sleeping function from atomic context if
power_supply_put() is called from atomic context.
