HID: roccat: pyra: reject short button reports
The raw event callback runs before HID core validates and zero-pads the
report. It passes the buffer to helpers which inspect data[0] and read a
complete struct pyra_mouse_event_button for button reports. A truncated
report can therefore cause an out-of-bounds read.
Require enough data for the button report before calling either helper.
Commit 47669bec44fe ("HID: asus: refactor the two workqueues and init
sequence") added the same kind of raw-event length validation to hid-asus.
Fixes: cb7cf3da0daa ("HID: roccat: add driver for Roccat Pyra mouse")
