spi: offload: remove unnecessary check on trigger->ops

Considering that trigger->ops = NULL happens only when the trigger is
being removed from the list, and at that point the operation is protected
with the spi_offload_triggers_lock, it is possible to remove the
!trigger->ops check because it will never be true in
spi_offload_trigger_get()
