media: dvb-frontends: m88ds3103: Fix a memory leak in an error handling path of m88ds3103_probe() 

[ Upstream commit 5b2f885e2f ]

If an error occurs after a successful i2c_mux_add_adapter(), then
i2c_mux_del_adapters() should be called to free some resources, as
already done in the remove function.
