[PATCH] HID: rmi: replace ternary operator with min()

[Jiangshan Yi]

From: Jiangshan Yi <yijiangshan@xxxxxxxxxx>

Fix the following coccicheck warning:

drivers/hid/hid-rmi.c:240: WARNING opportunity for min().
drivers/hid/hid-rmi.c:350: WARNING opportunity for min().

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