asoc: swr-haptics: keep in SWR PLAY_SRC when disabling SWR play

Currently, 0 is written into SWR_PLAY register when disabling SWR play,
it coincidently updates the PLAY_SRC to FIFO mode and disables it. If
there is a FIFO play triggered from SPMI address space, the FIFO play
will be disabled and the FIFO samples will be flushed. To avoid this,
keep in SWR PLAY_SRC when disabling SWR play.
