Jason Gunthorpe 3cb2482714 vfio/mbochs: Fix close when multiple device FDs are open
mbochs_close() iterates over global device state and frees it. Currently
this is done every time a device FD is closed, but if multiple device FDs
are open this could corrupt other still active FDs.

Change this to use close_device() so it only runs on the last close.
