Missing info for filesystem credential check on bulk deletion of themes in Multisite

Context: Bulk deleting Themes in Network Admin.
When checking for filesystem credentials in delete_theme(), the redirect url is missing information about the files to delete, since it is passed through POST and not GET.
I experienced it in 3.3.2 and it still occurs in the latest nightly build.
