[PATCH 5.10 278/381] afs: Fix updating of i_size with dv jump from server

[Greg Kroah-Hartman]

From: Marc Dionne <marc.dionne at auristor.com>

[ Upstream commit d7f74e9a917503ee78f2b603a456d7227cf38919 ]

If the data version returned from the server is larger than expected,
the local data is invalidated, but we may still want to note the remote
file size.

Since we're setting change_size, we have to also set data_changed
for the i_size to get updated.
