Fix maximum connections reached for BLE

There was a patch some time ago:
https://android.googlesource.com/platform/system/bt/+/3c7bb20d104919837cc32e1e8c214003f583ddc0



But that patch assumes the error code sent is Connection Rejected Due
To Limited Resources. Most controllers however send Connection Limit
Exceeded, which is more correct. This patch accept both error codes.
