afs: Fix non-setting of mtime when writing into mmap
[ Upstream commit bb413489288e4e457353bac513fddb6330d245ca ]
The mtime on an inode needs to be updated when a write is made into an
mmap'ed section. There are three ways in which this could be done: update
it when page_mkwrite is called, update it when a page is changed from dirty
to writeback or leave it to the server and fix the mtime up from the reply
to the StoreData RPC.
Found with the generic/215 xfstest.
Fixes: 1cf7a1518aef ("afs: Implement shared-writeable mmap")
