[Patch] - apr_recvfrom on Win32 returns 730022 instead of blocking as expected

[Henry Jen]

Hi,

Attached patch fix a bug on Win32, if call apr_recvfrom() when no one
write to that addr:port, the call returns 730022(WSAEINVAL) instead of
blocking as expected.

The reason is that the from->salen was not initialized properly. The
patch fix the problem.

I tested on Windows XP home with apr-0.9.6.

Cheers,
