p54spi: Fix workqueue deadlock
commit 2d1618170eb493d18f66f2ac03775409a6fb97c6 upstream.
priv->work must not be synced while priv->mutex is locked, because
the mutex is taken in the work handler.
Move cancel_work_sync down to after the device shutdown code.
This is safe, because the work handler checks fw_state and bails out
early in case of a race.
