net: usbnet: fix tx_dropped statistics
It is normal for minidrivers accumulating frames to return NULL from their tx_fixup function. We do not want to count this as a drop, or log any debug messages. A different exit path is therefore chosen for such drivers, skipping the debug message and the tx_dropped increment. The test for accumulating drivers was however completely bogus, making the exit path selection depend on whether the user had enabled tx_err logging or not. This would arbitrarily mess up accounting for both accumulating and non-accumulating minidrivers, and would result in unwanted debug messages for the accumulating drivers. Fix by testing for FLAG_MULTI_PACKET instead, which probably was the intention from the beginning. This usage match the documented behaviour of this flag: Indicates to usbnet, that USB driver accumulates multiple IP packets. Affects statistic (counters) and short packet handling.
