media: platform: samsung: s5p-jpeg: replace ternary operator with max()

Fix the following coccicheck warning:

drivers/media/platform/samsung/s5p-jpeg/jpeg-core.c:1712:24-25:
WARNING opportunity for max()

max() macro is defined in include/linux/minmax.h. It avoids multiple
evaluations of the arguments when non-constant and performs strict
type-checking.
