[CIFS] Fix oops in cifs_create when nfsd server exports cifs mount
nfsd is passing null nameidata (probably the only one doing that) on call to create - cifs was missing one check for this. Note that running nfsd over a cifs mount requires specifying fsid on the nfs exports entry and requires mounting cifs with serverino mount option. Signed-off-by: Steve French <sfrench@us.ibm.com>
