Bluetooth: Fix slab-out-of-bounds read in hci_extended_inquiry_result_evt()
commit 51c19bf3d5cfaa66571e4b88ba2a6f6295311101 upstream.
Check upon `num_rsp` is insufficient. A malformed event packet with a
large `num_rsp` number makes hci_extended_inquiry_result_evt() go out
of bounds. Fix it.
This patch fixes the following syzbot bug:
