Jaganath Kanakkassery 7b064edae3 Bluetooth: Fix authentication if acl data comes before remote feature evt 
If remote device sends l2cap info request before read_remote_ext_feature
completes then mgmt_connected will be sent in hci_acldata_packet() and
remote name request wont be sent and eventually authentication wont happen

This patch moves sending mgmt_connected from hci_acldata_packet() to
l2cap_connect_req() since this code is to handle the scenario remote
device sends l2cap connect req too fast
