Pete Zaitcev 204d8fb1b4 USB: fix usbmon BUG trigger 
commit 46eb14a6e1 upstream.

Automated tests triggered this by opening usbmon and accessing the
mmap while simultaneously resizing the buffers. This bug was with
us since 2006, because typically applications only size the buffers
once and thus avoid racing. Reported by Kirill A. Shutemov.
