usb: ldusb: replace ternary operator with max_t()

Fix the following coccicheck warning:

drivers/usb/misc/ldusb.c:719: WARNING opportunity for max().
drivers/usb/misc/ldusb.c:721: WARNING opportunity for max().

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