- Return 0 from mdev open_device if there is no op
- Fix style for else {}
- Spelling fix for singleton
- Acquire cur_mem under lock
- Always use error unwind flow for vfio_pci_check_all_devices_bound()

This implementation uses xarray instead of searching through the driver
core structures, which simplifies the somewhat tricky locking in this
