libertas_tf: don't set URB_ZERO_PACKET on IN USB transfer

BugLink: https://bugs.launchpad.net/bugs/1821607
commit 607076a904c435f2677fadaadd4af546279db68b upstream.

It doesn't make sense and the USB core warns on each submit of such
URB, easily flooding the message buffer with tracebacks.

Analogous issue was fixed in regular libertas driver in commit 6528d8804780
("libertas: don't set URB_ZERO_PACKET on IN USB transfer").
