omap-keypad: fix build warning

From: David Brownell <[email protected]>

Build fixes:

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.

Applied, thank you David.
