iio:adc:vf610 ensure correct handing of interruption of wait for completion
Issue highlighted by smatch warning:
CHECK drivers/iio/adc/vf610_adc.c
drivers/iio/adc/vf610_adc.c:466 vf610_read_raw() warn: unsigned 'ret' is never less than zero.
As wait_for_completion_interruptible_timeout can return -ERESTARTSTSYS, if
interrupted, ret must be signed.
