Fix mpls maximum labels list parsing up to MAX_MPLS_LABELS/16 entries (instead of up to MAX_MPLS_LABELS - 1).

Addresses the following:

$ echo "mpls 00000f00,00000f01,00000f02,00000f03,00000f04,00000f05,00000f06,00000f07,00000f08,00000f09,00000f0a,00000f0b,00000f0c,00000f0d,00000f0e,00000f0f" > /proc/net/pktgen/lo@0 -bash: echo: write error: Argument list too long
