[ Upstream commit 247f226adadfb7be09dd537f177429f4415aef8e ]

Set HCI_QUIRK_BROKEN_ERR_DATA_REPORTING for QCA controllers since
they answer HCI_OP_READ_DEF_ERR_DATA_REPORTING with error code
"UNKNOWN HCI COMMAND" as shown below:

[ 580.517552] Bluetooth: hci0: unexpected cc 0x0c5a length: 1 < 2
[ 580.517660] Bluetooth: hci0: Opcode 0x c5a failed: -38

hcitool -i hci0 cmd 0x03 0x5a
< HCI Command: ogf 0x03, ocf 0x005a, plen 0
> HCI Event: 0x0e plen 4
01 5A 0C 01

btmon log:
< HCI Command: Read Default Erroneous Data Reporting (0x03|0x005a) plen 0
> HCI Event: Command Complete (0x0e) plen 4
Read Default Erroneous Data Reporting (0x03|0x005a) ncmd 1
