Bluetooth: btintel_pcie: fix off-by-one bounds check in RX submit
btintel_pcie_submit_rx() used frbd_index > rxq->count to guard the
FRBD array access, allowing frbd_index == rxq->count to pass through
and index one element past the end of the array. Change the check to
>= rxq->count so every out-of-range index is rejected.
This issue was reported by Claude Mythos.
