net: USB: Fix wrong-direction WARNING in plusb.c

The syzbot fuzzer detected a bug in the plusb network driver: A
zero-length control-OUT transfer was treated as a read instead of a
write.  In modern kernels this error provokes a WARNING:

usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType c0

The fix is to call usbnet_write_cmd() instead of usbnet_read_cmd() and
remove the USB_DIR_IN flag.
