Subject: [EDT][PATCH] ax88179_178a: add reset function in reset_resume

EP-EC562D6B53594479BCA6FC73F17DEE54
Without reset functionality in reset_resume, iperf connection
does not establish after suspend/resume however ping works at
the same time.

reset function inside reset_resume solves above bug. We have verified
it on ASIX based ST Lab, Cadyce dongle.
