spi: mpc512x-psc: fix compiler warning about uninitialized variable

This fixes several warnings like:

	drivers/spi/spi-mpc512x-psc.c: In function 'mpc512x_psc_spi_prep_xfer_hw':
	arch/powerpc/include/asm/io.h:163:2: warning: '__ret' may be used uninitialized in this function [-Wmaybe-uninitialized]

introduced in commit 8bf960985dfc for some build configurations.
