Bluetooth: qca: Fix triggering coredump implementation
[ Upstream commit6abf9dd26b
] hci_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(). Fixes:06d3fdfcdf
