[Spice-devel] [PATCH] Fix = use instead of ==

[Christophe Fergeau]

When checking for ConnectNamedPipe status, the error check uses
if ( err = ERROR_IO_PENDING) instead of using == which causes this
error check to always trigger. This commit fixes this, however it
needs careful testing since the fact that it went unnoticed means
the code with the bug was working as expected. Maybe changing it
will cause unexpected regressions.
