Joerg Roedel c6362a74da x86/sev: Split up runtime #VC handler for correct state tracking 
[ Upstream commit be1a540886 ]

Split up the #VC handler code into a from-user and a from-kernel part.
This allows clean and correct state tracking, as the #VC handler needs
to enter NMI-state when raised from kernel mode and plain IRQ state when
raised from user-mode.

Fixes: 62441a1fb5 ("x86/sev-es: Correctly track IRQ states in runtime #VC handler")
