HID: Intel-thc-hid: Intel-quickspi: Fix buffer overflow

Browse source

The input buffers are used to store complete HID-over-SPI packets,
including their protocol headers. However, their sizes are
currently calculated from the payload length only.

Allocate enough space for both the payload and the packet header to
prevent a buffer overflow when the payload reaches its maximum size.
