iio: buffer: Fix uninitialized variable ret

Browse Source 
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")
