[patch] spi: pic32-sqi: silence array overflow warning

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

We read one element beyond the end of the array when we access
"rdesc[i + 1]" so it causes a static checker warning.  It's harmless
because we write over it again on the next line.  But let's just silence
the warning.
