drivers: spi_nrfx_spis: Fix obtaining dev pointer in event handler

Browse source 
This is a follow-up to commit 4c20403629.

CONTAINER_OF() cannot be used to obtain the device pointer from its
data pointer as this data is not contained in the device structure.
Instead, use a dedicated member in the device data structure to store
the device pointer.
