[ChenTao]

Fix the following warning:

'mode' and 'library' are u32, they are never be negative,
DRV260X_LRA_MODE and DRV260X_LIB_EMPTY are 0x00, the comparison
is always false.

drivers/input/misc/drv260x.c:478:20: warning:
comparison of unsigned expression < 0 is always false [-Wtype-limits]
  if (haptics->mode < DRV260X_LRA_MODE ||
drivers/input/misc/drv260x.c:490:23: warning:
comparison of unsigned expression < 0 is always false [-Wtype-limits]
  if (haptics->library < DRV260X_LIB_EMPTY ||
