spi: spi-ti-qspi: fix warning
drivers/spi/spi-ti-qspi.c: In function ‘ti_qspi_start_transfer_one’: drivers/spi/spi-ti-qspi.c:392:8: warning: ‘rx_wlen’ may be used uninitialized in this function [-Wmaybe-uninitialized] 392 | if (rx_wlen >= 32) | ^ drivers/spi/spi-ti-qspi.c:318:12: note: ‘rx_wlen’ was declared here 318 | u8 rxlen, rx_wlen; | ^~~~~~~ The warning is a false positive; it is not thrown by all compiler versions, e.g. Red Hat Cross 9.2.1-1 but not Linaro GCC 7.5-2019.12.
