libcamera: device_enumerator_udev: Remove devnum from dependency map

Browse source 
Previously, after `addV4L2Device()` had seen all dependecies, it would
remove the `MediaDeviceDeps` object from the `pending_` list, which
would result in it being destroyed. However, there would still be
(dangling) pointers to this object in `devMap_` that were added in
`addUdevDevice()` (line 103). So remove the entry with the given devnum
when it is removed from the corresponding `MediaDeviceDeps` object.
