spi: sn-f-ospi: Fix division by zero
[ Upstream commit 3588b1c0fde2f58d166e3f94a5a58d64b893526c ]
When there is no dummy cycle in the spi-nor commands, both dummy bus cycle
bytes and width are zero. Because of the cpu's warning when divided by
zero, the warning should be avoided. Return just zero to avoid such
calculations.
