[PATCH] device: Fix calling DisconnectProfile DBus call with disconnected profile UUID

["Pali Rohár" <pali@kernel.org>]

When DisconnectProfile is called with disconnected UUID, bluetooth daemon
often returned error "Operation already in progress". This change fixed it
and no error message is returned for this case.
