spi: spi-mem: Fix inverted logic in op sanity check
[ Upstream commit aea3877e24f3acc6145094848dbb85f9ce85674a ]
On r8a7791/koelsch:
m25p80 spi0.0: error -22 reading 9f
m25p80: probe of spi0.0 failed with error -22
Apparently the logic in spi_mem_check_op() is wrong, rejecting the
spi-mem operation if any buswidth is valid, instead of invalid.
Fixes: 380583227c0c7f52 ("spi: spi-mem: Add extra sanity checks on the op param")
