Casey Bodley 794dfeca49 name cache: lookup semantics match nfs41_lookup() on NOENT 
previously, when the name cache encountered a missing/negative/expired entry, it returned the previous two entries as 'target' and 'parent', and nfs41_lookup() started new lookups from the filehandle in 'target'.  this differs from nfs41_lookup(), which on NOENT will return NULL for the 'target' and the previous entry as 'parent'.  modified name_cache_lookup() to do the same, and updated nfs41_lookup() to start new lookups from the filehandle in 'parent'

now when nfs41_lookup() gets the is_negative flag from nfs41_name_cache_lookup(), it can just return the error without needing to copy the 'target' to 'parent'
