Bluetooth: qca: Fix triggering coredump implementation

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().
