s3: nmbd: Fix bug 10633 - nmbd denial of service
The Linux kernel has a bug in that it can give spurious
wakeups on a non-blocking UDP socket for a non-deliverable packet.
When nmbd was changed to use non-blocking sockets it
became vulnerable to a spurious wakeup from poll/epoll.
Fix sys_recvfile() to return on EWOULDBLOCK/EAGAIN.
CVE-2014-0244
