net: caif: Use netif_rx_any_context()
The usage of in_interrupt() in non-core code is phased out. Ideally the
information of the calling context should be passed by the callers or the
functions be split as appropriate.
cfhsi_rx_desc() and cfhsi_rx_pld() use in_interrupt() to distinguish if
they should use netif_rx() or netif_rx_ni() for receiving packets.
The attempt to consolidate the code by passing an arguemnt or by
distangling it failed due lack of knowledge about this driver and because
the call chains are hard to follow.
As a stop gap use netif_rx_any_context() which invokes the correct code path
depending on context and confines the in_interrupt() usage to core code.
