Subject: [PATCH] media: Fix get_key_haup_common.isra.4() debug message to print ptoggle value

Fix the debug message in get_key_haup_common.isra.4() doesn't print the
correct toggle value. Fix it. This shows up as an used uninitialized warn
message:

drivers/media/i2c/ir-kbd-i2c.c: In function ‘get_key_haup_common.isra.4’:
 drivers/media/i2c/ir-kbd-i2c.c:62:2: warning: ‘toggle’ may be used uninitialized in this function [-Wmaybe-uninitialized]
   printk(KERN_DEBUG MODULE_NAME ": " fmt , ## arg)
   ^~~~~~
 drivers/media/i2c/ir-kbd-i2c.c:70:20: note: ‘toggle’ was declared here
   int start, range, toggle, dev, code, ircode, vendor;
                     ^~~~~~
