KVM: SVM: Allocate IR data using atomic allocation
commit 7537deda36521fa8fff9133b39c46e31893606f2 upstream.
Allocate SVM's interrupt remapping metadata using GFP_ATOMIC as
svm_ir_list_add() is called with IRQs are disabled and irqfs.lock held
when kvm_irq_routing_update() reacts to GSI routing changes.
Fixes: 411b44ba80ab ("svm: Implements update_pi_irte hook to setup posted interrupt")
