[Bug 252165] usb network and mii bus media status race condition

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252165

(In reply to Mikael Urankar from comment #42)

I can still reproduce with both patches the state down/up issue. 

The patch solves tick vs ioctl. But running 2 or ifconfig from different
screens lead to the issue (ioctl thread1 vs ioctl thread2), since
usbd_do_request_flags releases the lock and so one of the ioctl thread waiting
for it gets executed, altering the media_state flag.

I will try to dedicate some time for it to see how this can be solved.
