Fix zpl_revalidate() NULL deref

In zpl_revalidate() it's possible for the nameidata to be NULL
for kernels which still accept the parameter.  In particular,
lookup_one_len() calls d_revalidate() with a NULL nameidata.

Resolve the issue by checking for a NULL nameidata in which case
just set the flags to 0.

Closes #1226
