4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit e90202ed1cf9672c48a363c84a929932ebfe6fc0 ]
The TC received from APP TLV is stored in offload_tc, and should not be
set by protocols which did not receive an APP TLV. Fixed the condition
when overriding the offload_tc.
