vmwgfx: Bump major
This bumps driver major version as a result of previous incompatible interface changes. In addition, a leftover command definition is removed from the vmwgfx_drm.h header. Also a strict version check is enforced on the exebuf ioctl. This is intended to be the last major bump before exiting staging.
