[PATCH] ax88179_178a: add reset functionality in reset_resume

[Vivek Kumar Bhagat]

Without reset functionality in reset_resume, iperf connection
does not establish after suspend/resume however ping works at
the same time. iperf connection fails by giving checksum error
in tcpdump.

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