i2c: mux: Avoid potential false error message in i2c_mux_add_adapter

Browse Source 
[ Upstream commit b13e59e74f ]

I2C_CLASS_DEPRECATED is a flag and not an actual class.
There's nothing speaking against both, parent and child, having
I2C_CLASS_DEPRECATED set. Therefore exclude it from the check.
