lldp: fix a buffer overflow when handling management address TLV

When a remote device was advertising a too large management address
while still respecting TLV boundaries, lldpd would crash due to a buffer
overflow. However, the buffer being a static one, this buffer overflow
is not exploitable if hardening was not disabled. This bug exists since
version 0.5.6.
