drivers/i2c/w83795: Fix tautology from wrong return type

The correct type-signature of 'do_smbus_write_byte' is:

int do_smbus_write_byte(u32 smbus_io_base, u32 device, u32 address, u8 val)

and so storing the return type in a 'u32' is inappropriate, leading
    to a tautological compare of 'ret < 0' and 'err < 0'.
