Input: omap-keypad - fix build warning
Fix the following build warning:
drivers/input/keyboard/omap-keypad.c: In function 'omap_kp_probe':
drivers/input/keyboard/omap-keypad.c:418: warning: 'row_idx' is used uninitialized in this function
drivers/input/keyboard/omap-keypad.c:421: warning: 'col_idx' is used uninitialized in this function
These variables are useful when cpu_is_omap24xx(), and otherwise just
for useless cleanup.
