[PATCH 7/8] [media] ddbridge: detach first input if the second one failed to init

[Daniel Scheller <d.scheller.oss@gmail.com>]

From: Daniel Scheller <d.scheller@gmx.net>

In ddb_ports_attach(), if the second input of a dual tuner failed to
initialise, the first one can be detached (and resources be freed) as
this will be counted as the whole port having failed to initialise,
thus the first one won't be used anyway.
