[PATCH 04/10] fs: cifs: Replace CURRENT_TIME with ktime_get_real_ts()

[Deepa Dinamani <deepa.kernel@gmail.com>]

This is in preparation for the series that transitions
filesystem timestamps to use 64 bit time and hence make
them y2038 safe.

CURRENT_TIME macro will be deleted before merging the
aforementioned series.

Filesystem times will use current_fs_time() instead of
CURRENT_TIME.
Use ktime_get_real_ts() here as this is not filesystem time.
ktime_get_real_ts() returns the timestamp in ns which can
be used to calculate network time for NTLMv2 authentication
timestamp.
