Revert "x86/speculation: Add RSB VM Exit protections"

This reverts commit 3f2ae9fe6dc55216cfbb2b0c8318a87210976906.

This is commit bef8fbe81a3f897c77d357abbd182e3c21f9db8b upstream.

In order to apply IBRS mitigation for Retbleed, PBRSB mitigations must be
reverted and the reapplied, so the backports can look sane.
