[patch 2.6.25-rc8] omap-keypad: fix build warning

[David Brownell]

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.
