iio: buffer: Fix uninitialized variable ret
When !iio_buffer_space_available(rb) is true and signal_pending(current)
is false the end of the do-while loop is reached and the uninitialized
variable ret is zero checked. Fix this by initializing variable ret to
zero.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 9eeee3b0bf19 ("iio: Add output buffer support")
