iio: gyro: mpu3050: Make mpu3050_common_remove() return void
This function (up to now) returns zero unconditionally, so there isn't
any benefit of returning a value. Make it return void to be able to see
at a glance that the return value of mpu3050_i2c_remove is always zero.
This patch is a preparation for making i2c remove callbacks return void.
