commit 456b59e757b0c558df550764a4fd5ae6877e93f8 upstream.
ovl_change_flags() is an open-coded variant of fs/fcntl.c:setfl() and it
got missed by commit 164f4064ca81 ("keep iocb_flags() result cached in
struct file"); the same change applies there.

Fixes: 164f4064ca81 ("keep iocb_flags() result cached in struct file")
