vfio-pci: Fix remove path locking
Locking both the remove() and release() path results in a deadlock
that should have been obvious. To fix this we can get and hold the
vfio_device reference as we evaluate whether to do a bus/slot reset.
This will automatically block any remove() calls, allowing us to
remove the explict lock. Fixes 61d792562b53.
