Subject: [PATCH] Fix "GATT Read Multiple Variable Response" builder
0 length value is perfectly fine, and should result in just length
added into the packet.
Currently, for 0 length value we just break out of loop, and don't add
any value.
This means, that if first characetristic in response had 0 length, we
would return empty packet.
Ignore-AOSP-First: security fix
Test: mma -j32;
Bug: 352696105
Bug: 356886209
Flag: exempt, obvious logic fix
