    x86/EFI: fix FPU state handling around runtime calls
    There are two issues.  First, the nonlazy xstates were never restored
    after returning from the runtime call.
    Secondly, with the fully_eager_fpu mitigation for XSA-267 / LazyFPU, the
    unilateral stts() is no longer correct, and hits an assertion later when
    a lazy state restore tries to occur for a fully eager vcpu.
    Fix both of these issues by calling vcpu_restore_fpu_eager().  As EFI
    runtime services can be used in the idle context, the idle assertion
    needs to move until after the fully_eager_fpu check.
    Introduce a "curr" local variable and replace other uses of "current"
    at the same time.
