libertas: fix data packet size errors
I wondered about junk bytes at the end when using "lbsdebug +hex +host"
until I noticed that firmware for the CF card sends my extranous bytes.
It says "I have 20 bytes", I take 20 bytes, but the last 8 bytes of this
are just data junk.
Also, in the new lbs_cmd() where was a size miscalulation
that made itself clear after fixing this bug.
