Bluetooth: hci_event: Fix handling of HCI_EV_IO_CAPA_REQUEST
[ Upstream commit 7e74aa53a68bf60f6019bd5d9a9a1406ec4d4865 ]
If we received HCI_EV_IO_CAPA_REQUEST while
HCI_OP_READ_REMOTE_EXT_FEATURES is yet to be responded assume the remote
does support SSP since otherwise this event shouldn't be generated.
