nfs_nfsdstate.c: Add sanity checks for lock stateidsHEADmain

Bugzilla PR reported a crash caused by a synthetic client
doing a Lock operation request with a delegation stateid.

This patch fixes the problem by adding sanity checks
for the type of stateid provided as an argument to the
Lock and LockU operations.

It has been tested with the FreeBSD, Linux and Solaris 11.4
clients.  Hopefully, other NFSv4 clients will work ok
as well.
