MFD: twl6040-codec: cancel synch all active works on suspend
The TWL6040 vib_update work has to be canceled synchronously
before continue suspending, because of:
- it may sleep while accessing to I2C bus and, as result, WFI may be
reached in the middle of its execution and that may prevent system
from entering to OFF state.
- the device suspend handler may switch TWL6040 device to sleep
state while vib_update work is still active.
