pnfs/flexfiles: retry getting layout segment for reads
commit eb3fabde15bccdf34f1c9b35a83aa4c0dacbb4ca upstream.
If ff_layout_pg_get_read()'s attempt to get a layout segment results
in -EAGAIN have ff_layout_pg_init_read() retry it after sleeping.
If "softerr" mount is used, use 'io_maxretrans' to limit the number of
attempts to get a layout segment.
This fixes a long-standing issue of O_DIRECT reads failing with
-EAGAIN (11) when using flexfiles Client Side Mirroring (CSM).
