[PATCH v1 1/1] spi: Don't overwrite num_chipselect with error code

The code currently organized in a way that num_chipselect is overwritten each time we call spi_get_gpio_descs(). It might be potentially dangerous in case when the gpiod_count() returns an error code. Note, that gpiod_count() never returns 0, take this into account as well. Fixes: f3186dd87669
