vmwgfx: Update stand alone to v4.11

* Skipped update to drm_mm and drm_vma_manager because the switch to
  using interval tree makes porting difficult.

* Added memdup_user_nul(), but replaced kmalloc_track_caller() with
  kmalloc() due to a compilation error.

* Removed building and usage of debugfs_crc

* VMWGFX_COMPAT_NO_VAF no longer seems to be required

* Tested on
    CentOS 6.5, RHEL 6.8: 2.6.32-696
    RHEL 7.3: 3.10.0-514
    Ubuntu 14.04: 4.2.0-35
    Ubuntu 16.04: 4.4.0-78
    Ubuntu 16.04: 4.12-rc1
