Input: evdev - fix EVIOCG{type} ioctl

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

The 'max' size passed into the function is measured in number of bits
(KEY_MAX, LED_MAX, etc) so we nedd to convert it accoidingly before tyring

###                           need               accordingly(?)     trying

to copy the data out, otherwise we will try copying too much and end up
with up with a page fault.
