PROBLEM:
performance.nfs.* option values (which are of type boolean) are
not validated during the stage phase of 'volume set'.
The result - nfs graph generation fails during commit phase,
AFTER the option and its (invalid) value have been placed in
volinfo->dict.
CAUSE:
nfsperfxl_option_handler() - the function that validates the values of
performance.nfs.* options - never receives the (key,value) pair that
needs to be set, for validation during 'volume set' stage.
FIX:
In build_nfs_graph(), copy the (mod_)dict containing the (option,value)
parameters into set_dict before attempting to build the client graph
for the volume on which the operation is being performed.
Of course, an easier way out would be to simply do a 'volume reset' and
pretend nothing wrong happened!
