Return errno values rather than dying VM_PAGER_* in the pgo_fault() interfaces.

This doesn't introduce any value change. All errors are converted to EACCES
even if many could use EIO.

While here put some KERNEL_ASSERT_LOCKED() in the functions called from

many comments are lying.

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to

Adds support for more Intel hardware:

Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).
