iio: light: si1133: reset counter to prevent race condition
Sashiko reported a potential race condition happening when the driver
returns an errno after a timeout in the si1133_command() function. The
premature exit causes the hardware and software counters to become out
of sync by not updating data->rsp_seq, therefore the internal hardware
counter keeps incrementing.
Fix this by adding a call to si1133_cmd_reset_counter() before returning
from timeout.
