media: lgdt3306a: Fix module count mismatch on usb unplug

[ Upstream commit 835d66173a38538c072a7c393d02360dcfac8582 ]

When used as an i2c device there is a module usage count mismatch on
removal, preventing the driver from being used thereafter. dvb_attach
increments the usage count so it is properly balanced on removal.

On disconnect of Hauppauge SoloHD/DualHD before:

lsmod | grep lgdt3306a
lgdt3306a              28672  -1
i2c_mux                16384  1 lgdt3306a

On disconnect of Hauppauge SoloHD/DualHD after:

lsmod | grep lgdt3306a
lgdt3306a              28672  0
i2c_mux                16384  1 lgdt3306a
