Subject: [PATCH] libertas_tf: don't set URB_ZERO_PACKET on IN USB transfer
Git-commit: 607076a904c435f2677fadaadd4af546279db68b
Patch-mainline: v5.1-rc1
References: bsc#1051510

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").
