	spi: tegra114: Don't fail set_cs_timing when delays are zero
The original code would skip null delay pointers, but when the pointers
were converted to point within the spi_device struct, the check was not
updated to skip delays of zero. Hence all spi devices that didn't set
delays would fail to probe.
Fixes: 04e6bb0d6b ("spi: modify set_cs_timing parameter")
