Szymon Janc ac363cf9eb Bluetooth: Fix sending Read Remote Extended Features command 
This command should only be used if remote device reports that it
supports extended features. Otherwise command will fail and connection
will be dropped.

Some devices support SSP but don't support extended features so
current check for SSP support is not enought.

Instead of checking for SSP support just check if both ends support
Extended Feature.
