KVM: Fix segment descriptor loading
commit c697518a861e6c43b92b848895f9926580ee63c3 upstream
Add proper error and permission checking. This patch also change task
switching code to load segment selectors before segment descriptors, like
SDM requires, otherwise permission checking during segment descriptor
loading will be incorrect.
