orangefs: fix deadlock; do not write i_size in read_iter
commit 6793f1c450b1533a5e9c2493490de771d38b24f9 upstream.
After do_readv_writev, the inode cache is invalidated anyway, so i_size
will never be read. It will be fetched from the server which will also
know about updates from other machines.
Fixes deadlock on 32-bit SMP.
