Bluetooth: btusb: Fix triggering coredump implementation for QCA
[ Upstream commit b23d98d46d2858dcc0fd016caff165cbdc24e70a ]
btusb_coredump_qca() uses __hci_cmd_sync() to send a vendor-specific
command to trigger firmware coredump, but the command does not
have any event as its sync response, so it is not suitable to use
__hci_cmd_sync(), fixed by using __hci_cmd_send().
