Commit d224f05fcf pre-parsed the next operation number for
the put file handle operations. This patch uses this next
operation number, plus the type of the file handle being set by
the put file handle operation, to implement the rules in RFC5661
Sec. 2.6 with respect to replying NFSERR_WRONGSEC.
This patch also adds a check to see if NFSERR_WRONGSEC should be
replied when about to perform Lookup, Lookupp or Open with a file
name component, so that the NFSERR_WRONGSEC reply is done for
these operations, as required by RFC5661 Sec. 2.6.
This patch does not have any practical effect for the FreeBSD NFSv4
client and I believe that the same is true for the Linux client,
since NFSERR_WRONGSEC is considered a fatal error at this time.
