e keep the nfs_inode->layout when the segs list is empty, and we remove it
from the nfs_client cl_layouts list, but we fail to reset the other fields.
Re-initialize the layout (all except for the refcount) so that the next
layoutget with potentially new deviceid.... sets the layout fields.

Note: API change to layoutdriver_io_operations free_layout

0001-SQUASHME-pnfs-submit-reinitialize-pnfs_layout_type.patch
0002-SQUASHME-pnfs-submit-file-layout-free_layout-init_on.patch

Tested

CONFIG_V4_I set:
Connectathon tests pass against GFS2/pNFS and pyNFS file layout servers. Both
return-on-close and not return-on-close tested.

CONFIG_V4_I not set:
NFSv4.0 mount passes Connectathon tests.
