Revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP"

commit 6fd2c17fb6e02a8c0ab51df1cfec82ce96b8e83d upstream.

This reverts commit 36a15e1cb134c0395261ba1940762703f778438c.

The usage of FLAG_SEND_ZLP causes problems to other firmware/hardware
versions that have no issues.

The FLAG_SEND_ZLP is not safe to use in this context.
See:
https://patchwork.ozlabs.org/project/netdev/patch/1270599787.8900.8.camel@Linuxdev4-laptop/#118378
The original problem needs another way to solve.

Fixes: 36a15e1cb134 ("net: usb: ax88179_178a needs FLAG_SEND_ZLP")
