spi: fsl-espi: avoid processing uninitalized data on error
When we get a spurious interrupt in fsl_espi_irq, we end up
processing four uninitalized bytes of data, as shown in this
warning message:
drivers/spi/spi-fsl-espi.c: In function 'fsl_espi_irq':
drivers/spi/spi-fsl-espi.c:462:4: warning: 'rx_data' may be used uninitialized in this function [-Wmaybe-uninitialized]
This adds another check so we skip the data in this case.
Fixes: 6319a68011b8 ("spi/fsl-espi: avoid infinite loops on fsl_espi_cpu_irq()")
