iio: adc: ti-ads1119: fix information leak in triggered buffer
The 'scan' local struct is used to push data to user space from a
triggered buffer, but it has a hole between the sample (unsigned int)
and the timestamp. This hole is never initialized.
Initialize the struct to zero before using it to avoid pushing
uninitialized information to userspace.
