staging: kpc2000: Fix a stack information leak in kp2000_cdev_ioctl()
The kp2000_regs struct has a 4 byte hole between ->hw_rev and ->ssid so
this could leak stack information to the user. This patch just memsets
the whole struct to zero.
Fixes: 7dc7967fc39a ("staging: kpc2000: add initial set of Daktronics drivers")
