zebra: untrusted array index (Coverity 1470113)

Browse Source 
This is a correction over 32ac96b2ba, so
removing the forced string null termination doesn't involve a worse situation
than before (the underflow check should protect for the case of receiving
an incomplete buffer, which would be the cause of non-zero terminated string)
