vfio/pci: Drain eventfd RCU callbacks on module exit
vfio_pci_eventfd_replace_locked() defers freeing replaced eventfds to
vfio_pci_eventfd_rcu_free(). A callback can remain queued after
close_device() returns and the device driver module reference is dropped.
Once the dependent driver is removed, vfio-pci-core can be unloaded while
the callback still points into its module text.
Wait for outstanding RCU callbacks before vfio-pci-core exits.
Fixes: 98693e0897f7 ("vfio/pci: Use RCU for error/request triggers to avoid circular locking")
