[PATCH libevdev 3/4] memcpy instead of invidual bittoggle

[Peter Hutterer]

The ioctls return the number of bytes copied into the destination, so just
copy them into the device state instead of individually flipping bits.

For easier review: rc is the return value of the EVIOCG* ioctl, which is
the number of bytes copied.
