two minor bugs in libosmo-abis

[jolly]

hi,

i fixed two obvious bugs in libosmo-abis. the first fix uses correct reference 
for mISDN interface number, the other handles variable frame lengths. both are 
tested. if nobody minds, i like to commit them.

regards,

andreas



Fixed wrong reference while opening mISDN socket

Fixed TRAU frame handling of packet lengths that are not a multiple of 4
