This patch fixes how the NFS client handles full NFS version 3 64-bit fileids.

Previously, messages of the form:
NFS3 LOOKUP: directory attributes from <servername> are of the wrong dir

would appear on the console when traversing an NFS version 3 server filesystem
that generated greater than 32-bit file ids.  This patch stores the full 64-bit
fileid (as specified by protocol) and uses that actual value to compare.
