include/npu.h: Remove unused struct npu_dev_trap
include/npu.h: Remove unused struct npu_dev_trap

Commit "0736df5 hw/npu: Use PCI virtual device" converted the npu over
to using some generic infrastructure to filter/intercept PCIe config
space writes. This made the original trap implementation redundant.
However it seems removal of the old struct definitions was missed
during the cleanup, so do that now.
