powerpc/powernv/npu: Prevent overwriting of pnv_npu2_init_contex() callback parameters
There is a single npu context per set of callback parameters. Callers
should be prevented from overwriting existing callback values so
instead return an error if different parameters are passed.
Fixes: 1ab66d1fbada ("powerpc/powernv: Introduce address translation services for Nvlink2")
