Subject: [PATCH] smb: fix modtime of multithread uploads by setting
 PartialUploads

Before this change PartialUploads was not set. This is clearly wrong
since incoming files are visible on the smb server.

Setting PartialUploads fixes the multithread upload modtime problem as
it uses the PartialUploads flag as an indication that it needs to set
the modtime explicitly.

This problem was detected by the new TestMultithreadCopy integration
tests

Fixes #7411
