kvm-x86: Remove eflags conversion into emulator format (Jan Kiszka) 

It seems that the conversion of the kernel-delivered eflags state into
qemu's internal split representation was once needed in an older kvm
design (register read-back may have taken place from inside cpu_exec).
Today it is plain wrong and causes incorrect cpu state reporting (gdb,
monitor) and should also corrupt its saving (savevm, migration). Drop
the related lines.
