[PATCH 6/9] target/i386: sev: Remove redundant cbitpos and reduced_phys_bits fields

[David Gibson]

The SEVState structure has cbitpos and reduced_phys_bits fields which are
simply copied from the SevGuestState structure and never changed.  Now that
SEVState is embedded in SevGuestState we can just access the original copy
directly.
