While execution of bt_disable there is missing de-initialization
of per_adv_sync_pool. If there was a sync in progress, (flags set
to BT_PER_ADV_SYNC_SYNCING) before bt_disable, then when the stack
is re-enabled by bt_enable new sync create fails.
The commit fixes the issue by new function that clears flags for
all per_adv_sync_pool entries. The function is executed by bt_disable.

The function get_per_adv_sync is used by HCI events to get
reference to periodic advertising sync object related with
handle available in handled events. Due to implementation
of Direction Finding event handlers in separate source file,
direction.c instead of putting in hci_core.c the function
get_per_adv_sync has to be globally accessible.
