nfsd: fix NFSv4 time_delta attribute

/*

 * ctime (in NFSv4, time_metadata) is not writeable, and the client

 * doesn't really care what resolution could theoretically be stored by

 * the filesystem.

 *

 * The client cares how close together changes can be while still

 * guaranteeing ctime changes.  For most filesystems (which have

 * timestamps with nanosecond fields) that is limited by the resolution

 * of the time returned from current_time() (which I'm assuming to be

 * 1/HZ).
