Input: tca8418 - remove set but not used variable 'max_keys'

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

drivers/input/keyboard/tca8418_keypad.c: In function tca8418_keypad_probe:
drivers/input/keyboard/tca8418_keypad.c:269:24: warning: variable max_keys set but not used [-Wunused-but-set-variable]

It's not used since commit 16ff7cb184 ("Input:
