Bugzilla Bug 110776

zd1211 kernel module fail to compile. It try to find "verify_area" kernel ksym,
but "verify_area" from linux kernel version up to 2.6.13 there's no more. Change
it to "access_ok" work.
At "www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg37872.html"
there's a explanation of URB_ASYNC_UNLINK use, set it to 0 is "a" solution (to
verify).
That's all. Goodbye.
