Revert "tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP ioctl call"

This reverts commit eec9fe7d1ab4a0dfac4cb43047a7657fffd0002f.

Ari writes as the reason this should be reverted:
	The problems with this patch include:
	1. There's at least one subtlety I overlooked - switching
	between X servers (i.e. from one X VT to another) still requires
	the cooperation of both X servers. I was assuming that KMS
	eliminated this.
	2. It hasn't been tested at all (no X server patch exists which
	uses the new mode).

As he was the original author of the patch, I'll revert it.
