Subject: PCI: vmd: Move SRCU cleanup after bus, child device removal

From: Jon Derrick <jonathan.derrick@intel.com>

commit 0cb259c47a4df466d641c1f07ae3eccaa9ba3ccb upstream.

Recent __call_srcu() changes have exposed that we need to cleanup SRCU
structures after pci_stop_root_bus() calls into vmd_msi_free().
