Input: set EV_ABS in dev->evbit even if input_alloc_absinfo() fails

The input core's error handling for input_alloc_absinfo() failures
is based on ignoring the error until input_register_device() runs
and then checks for the failure like this:

if (test_bit(EV_ABS, dev->evbit) && !dev->absinfo) {
dev_err(&dev->dev, ...);
return -EINVAL;
}

This relies on EV_ABS actually getting set in dev->evbit even
if input_alloc_absinfo() fails, change input_set_abs_params() and
input_set_capability() to actually adhere to this.
