glusterd: validate performance.nfs.* option values during volume set stage
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!
