pNFS: return status from nfs4_pnfs_ds_connect
The nfs4_pnfs_ds_connect path can call rpc_create which can fail or it can wait on another context to reach the same failure. This checks that the rpc_create succeeded and returns the error to the caller. When an error is returned, both the files and flexfiles layouts will return NULL from _prepare_ds(). The flexfiles layout will also return the layout with the error NFS4ERR_NXIO. Signed-off-by: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
