NFS: Don't use page_file_mapping after removing the page
[ Upstream commit d2ceb7e57086750ea6198a31fd942d98099a0786 ]
If nfs_page_async_flush() removes the page from the mapping, then we can't
use page_file_mapping() on it as nfs_updatepate() is wont to do when
receiving an error. Instead, push the mapping to the stack before the page
is possibly truncated.
Fixes: 8fc75bed96bb ("NFS: Fix up return value on fatal errors in nfs_page_async_flush()")
