The hci_send_req 100ms timeout is not enough when the chip is in deep
sleep.
The timeout value has been hardcoded on hci_send_req call and, instead,
it should be passed from above (for ex from hci_le_set_scan_enable).
This patch removes the hardcoded value from hci_send_req and it
increases the timeout to 1000ms.
