[PATCH] Input: xpad - fix input from Covert Forces Xbox One controller

[Cameron Gutman <aicommander@gmail.com>]

The Covert Forces edition of the Xbox One controller requires the full 5
byte initialization packet to work at all. The 5 byte packet was known to
be needed for proper rumble support, but it looks like it's needed even
without rumble on these controllers.
