Bluetooth: Fix slab-out-of-bounds read in hci_le_direct_adv_report_evt()
commit f7e0e8b2f1b0a09b527885babda3e912ba820798 upstream.
`num_reports` is not being properly checked. A malformed event packet with
a large `num_reports` number makes hci_le_direct_adv_report_evt() read out
of bounds. Fix it.
