sna: Mark the upload as having acquired the GTT mapping 

In order for the entire PutImage to be performed inplace, we need to
maintain the tendency to keep doing inplace operations. This hint is
provided by tracking whether or not the last operation used the GTT
mapping. However, that hint was not being provided by zpixmap_blt.
