xnest: Ignore GetImage() error in xnestGetImage() (v3)

(I found an amended version of this patch and applied the difference
here - keithp)

v3: Don't call Xsync before restoring error handler as any errors
    generated by XGetImage() should be processed when this call
    returns as suggested by Jamey Sharp <jamey@minilop.net>
