Joerg Roedel 67f66d48bd x86/sev: Split up runtime #VC handler for correct state tracking ...

[ Upstream commit be1a5408868af341f61f93c191b5e346ee88c82a ]

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.
