Input: olpc_apsp - remove set but not used variable 'np'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/input/serio/olpc_apsp.c: In function 'olpc_apsp_probe':
drivers/input/serio/olpc_apsp.c:192:22: warning:
 variable 'np' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit b56ece9a3ac3 ("Input: add OLPC
AP-SP driver")
