libertas: remove a coverity bug ... by removing an ill-conceived, useless line. Signed-off-by: Holger Schurig <[EMAIL PROTECTED]> --- Dunno how this line made it into the patch that I made in February and was commited in May. At that time, I didn't hardly knew anything about skb's at all and certainly didn't play with raw ethernet types. Maybe it was a remnant of some bugus test that I or the committer did?!?
