ctime: Fix ctime inconsisteny with utimensat
Problem:
When touch is used to create a file, the ctime is not matching
atime and mtime which ideally should match. There is a difference
in nano seconds.
Cause:
When touch is used modify atime or mtime to current time (UTIME_NOW),
the current time is taken from kernel. The ctime gets updated to current
time when atime or mtime is updated. But the current time to update
ctime is taken from utime xlator. Hence the difference in nano seconds.
Fix:
When utimesat uses UTIME_NOW, use the current time from kernel.
fixes: bz#1773530
