fix: Avoids IllegalArgumentException error.

We see from time to time: SEVERE: [10102681] RTPConnectorInputStream.runInReceiveThread#802: Failed to receive a packet:
                          java.lang.IllegalArgumentException: 'waitMillis' cannot be negative
                          	at org.bouncycastle.tls.DTLSTransport.receive(Unknown Source)
                          	at org.bouncycastle.tls.DTLSTransport.receive(Unknown Source)
                          	at org.jitsi.impl.neomedia.transform.dtls.DtlsPacketTransformer.reverseTransformDtls(DtlsPacketTransformer.java:901)

In BC 1.62 a check was added throwing the error if we pass -1, jvb passes 1 so we move to do the same.
