Subject: [PATCH 09/20] sysfs: Simplify iattr assignments

From: Eric W. Biederman <ebiederm@...ssion.com>

The granularity of sysfs time when we keep it is 1 ns.  Which
when passed to timestamp_trunc results in a nop.  So remove
the unnecessary function call making sysfs_setattr slightly
easier to read.
