KVM: task switch: use seg regs provided by subarch instead of reading from GDT
(cherry-picked from commit 34198bf8426276a2ce1e97056a0f02d43637e5ae)
There is no guarantee that the old TSS descriptor in the GDT contains
the proper base address. This is the case for Windows installation's
reboot-via-triplefault.
Use guest registers instead. Also translate the address properly.
