[PATCH 3/4] Revert "Bluetooth: hci_event: strip Broadcom vendor bits from legacy adv report type"

[Andre Eikmeyer <dev@deq.rocks>]

This reverts commit 88397423671f2b54119a6162a1834d207dcf1a81.

The commit clears the upper bits of the legacy LE Advertising Report
event type for every controller with manufacturer 15, Broadcom. The
reports of these bits, in its own commit message and here, all come
from the Broadcom controllers of the Apple T2 Macs.

The previous patch clears the bits in hci_bcm on Apple machines and in
hci_bcm4377, the drivers of these controllers, before the event reaches
the core. That makes the check in hci_le_adv_report_evt() redundant
for them.
