Bluetooth: HCI: Set extended advertising data synchronously

Bluetooth: HCI: Set extended advertising data synchronously

commit 89fb8acc38852116d38d721ad394aad7f2871670 upstream.

Currently, for controllers with extended advertising, the advertising
data is set in the asynchronous response handler for extended
adverstising params. As most advertising settings are performed in a
synchronous context, the (asynchronous) setting of the advertising data
is done too late (after enabling the advertising).

Move setting of adverstising data from asynchronous response handler
into synchronous context to fix ordering of HCI commands.

[ This patch deviates from the upstream version because 3 functions in
  hci_sync.c (hci_set_ext_adv_data_sync, hci_set_adv_data_sync and
  hci_update_adv_data_sync) had to be moved up within the file. The
  content of these functions differs between 6.6 and newer kernels. ]
