cli: Prevent creation of volumes with tokens as volnames

RCA:
yyparse confuses volnames with tokens when any of the
tokens 'volume', 'type', 'subvolumes', 'option', 'end-volume'
are used as volnames. This happens because io-stats xlator
name is same as volname in fuse volfile. Both nfs, fuse volfiles
are affected by this problem.

Fix:
We could fix this also by changing io-stats xlator name to
something other than 'volname'. But I am worried of the
backward compatibility issues it may introduce. Disallowing
creation of volumes with tokens as volname seems like a safer
fix.

Tests:
All volume creation operations with tokens as volname give
invalid volume name error.
