iio: fix config watermark initial value
config structure is set to 0 when updating the buffers, so by
default config->watermark will be 0. When computing the minimum
between config->watermark and the buffer->watermark or
insert_buffer-watermark, this will always be 0 regardless of the
value set by the user for the buffer.
Set as initial value for config->watermark the maximum allowed
value so that the minimum value will always be set from one of the
buffers.
