Unable to direct connect from Android DUT to Mynewt DUT

[EtienneRuffieux]

In test_btp_GAP_CONN_DCON_1, everything works until the tool set the Mynewt DUT in direct advertising and Android DUT tries to connect.

It seems that Mynewt successfully advertises, but there is a connection timeout when Android tries to read remote features. This timeout doesn't happen on the previous connection earlier in the test.

This could be an Android issue.
