x86: svm: Fix broken FS base on deactivation

After f93e23934b, we no longer call vmsave, thus will also not find the
right FS base there. This caused sporadic crashes of "jailhouse disable"
on return to userspace.

Fix it by loading the value from the corresponding MSR.

svm_handle_apic_access and vcpu_handle_mmio_access already do the
reporting.
