bug in A-bis OML wireshark dissector

[Pablo Neira Ayuso]

Hi!

While submitting the A-bis OML wireshark dissector I noticed one bug
in it that results in bogus message labeling.

The following patch should be applied to osmocom/wireshark.git tree.

P.S: I have submitted a patch to wireshark bugzilla that includes this
bugfix.
