Noel Eck 65fc70a31a rf22: Static analysis fixes
A few small fixes for the rf22 to satisfy klocwork.

    * Converted malloc's to new's to be more C++'ish and since
      malloc return were not checked.
    * Initialize data, buf, and _lastInterruptFlags
    * Up'ed RF22_MAX_MESSAGE_LEN to 64.
        Reason:

void RF22::sendNextFragment()
{
    if (_txBufSentIndex < _bufLen)
    {
    // Some left to send?
    uint8_t len = _bufLen - _txBufSentIndex;
    // But dont send too much
    if (len > (RF22_FIFO_SIZE - RF22_TXFFAEM_THRESHOLD - 1))
        len = (RF22_FIFO_SIZE - RF22_TXFFAEM_THRESHOLD - 1);
    spiBurstWrite(RF22_REG_7F_FIFO_ACCESS, _buf + _txBufSentIndex, len);
    _txBufSentIndex += len;
    }
}

        RF22_FIFO_SIZE = 64
        RF22_TXFFAEM_THRESHOLD = 4
        RF22_MAX_MESSAGE_LEN = 50
        _buf[RF22_MAX_MESSAGE_LEN]
        Length of _buf *was* 50, so if the 'But dont send too much' above
        was to happen, the length is set to 63, which overruns
        _buf[RF22_MAX_MESSAGE_LEN]
