media: vim2m: print device name after registering device

commit 143d75583f2427f3a97dba62413c4f0604867ebf upstream.

Move the v4l2_info() call displaying the video device name after the
device is actually registered.

This fixes a bug where the driver was always displaying "/dev/video0"
since it was reading from the vfd before it was registered.
