fix(ble): Improve timeout values

Instead of setting these values to 0, use the same settings as used in
lib/sdk/Libraries/BTLE/stack/ble-host/sources/stack/cfg/cfg_stack.c from
the Cordio SDK instead of 0.

In my small test these value sare not use in the normal pairing process,
so I think this is not fixing any problem.
