geo-rep: Do not use xsync_upper_limit for change detection

Use register time(xsync_upper_limit) only for stime update, do not
use for change detection.

Problem 1:
If a file created before geo-rep, xtime xattr does not exist.
Geo-rep updates xtime of the file to current time if not exists.
xtime > upper_limit so geo-rep will not pick those files. Changelog
either will have SETXATTR, and fails to sync the file.

Problem 2:
If a file is created before geo-rep create and updated after
geo-rep start. xtime of the file is greater than upper limit(geo-rep
start time/changelog register time). Geo-rep(XSync) will not pick this
file for syncing. Changelog will have only DATA recorded for that file.
Geo-rep tries DATA without any ENTRY ops and fails with rsync error.
