media: virtual-i2c-mux: Fix build for Linux v6.10

Browse Source 
In Linux v6.10, the 'class' argument was removed from the
i2c_mux_add_adapter() function. Add a test to conftest to detect the
correct number of arguments for i2c_mux_add_adapter() and update the
virtual-i2c-mux driver accordingly to fix the build for Linux v6.10.
