[PATCH 06/21] fs: udf: Replace CURRENT_TIME with current_fs_time()

[Deepa Dinamani]

CURRENT_TIME is not y2038 safe.

CURRENT_TIME macro is also not appropriate for filesystems
as it doesn't use the right granularity for filesystem
timestamps.

Logical Volume Integrity format is described to have the
same timestamp format for "Recording Date and time" as
the other [a,c,m]timestamps.
Hence using current_fs_time() instead here promises to
maintain the same granularity as other timestamps.

This is also in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe. As part of the effort current_fs_time() will be
extended to do range checks.
