vfs: deliver ACKs after config change

Browse Source 
This is needed to enable VFS plugins to notify VFS clients about file
changes that depend on the plugin configuration, E.g., whenever the vfs_ttf
plugin responds to a font-size change, it generates a watch notification
for the glyphs file. Since the change is independent from I/O, we need
to manually call 'handle_io_progress'.
