spi: fix counting in spi-loopback-test code
These variables are always used uninitialized:
drivers/spi/spi-loopback-test.c: In function 'spi_test_run_iter':
drivers/spi/spi-loopback-test.c:768:17: warning: 'rx_count' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/spi/spi-loopback-test.c:762:17: warning: 'tx_count' may be used uninitialized in this function [-Wmaybe-uninitialized]
Adding an explicit initialization seems to be the only
workable solution here, to make the code behave correctly
and build without warning.
