The newly added mpu3050 driver has two initializations for the
module owner, which causes a warning for 'make W=1':

include/linux/export.h:37:21: error: initialized field overwritten [-Werror=override-init]
drivers/iio/gyro/mpu3050-core.c:749:19: note: in expansion of macro 'THIS_MODULE'

This removes one of the two.
