spi: npcm: Fix uninitialized variable warning

The compiler has no way to know that rsize 1 or 2 are the only valid
values. Also simplify the code a bit with early return.

The warning was:

drivers/spi/spi-npcm-pspi.c:215:6: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
