drm/nouveau/mmu/gp100-: drop unneeded assignment in the if condition.
In order to keep the code style consistency of the whole file,
the 'inst' assignments should be deleted.
The clang_analyzer complains as follows:
drivers/gpu/drm/nouveau/nvkm/subdev/mmu/vmmgp100.c:499:8: warning:
Although the value storedto 'inst' is used in the enclosing expression,
the value is never actually read from 'inst'.
Karol: Removed unneeded brackets.

drm/nouveau/mmu: index engref by subdev type
None of the chipsets we use this on have instanced engines, so this is fine.

nouveau: fix storing invalid ptes
When migrating a range of system memory to device private memory, some of
the pages in the address range may not be migrating. In this case, the non
migrating pages won't have a new GPU MMU entry to store but the
nvif_object_ioctl() NVIF_VMM_V0_PFNMAP method doesn't check the input and
stores a bad valid GPU page table entry.
Fix this by skipping the invalid input PTEs when updating the GPU page
tables.

The nvif_object_ioctl() method NVIF_VMM_V0_PFNMAP wasn't correctly
setting the hardware specific GPU page table entries for 2MB sized
pages. Fix this by adding functions to set and clear PD0 GPU page
table entries.
