Martin Brandenburg 326efb49e1 orangefs: fix deadlock; do not write i_size in read_iter
commit 6793f1c450 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.
