Remove redundant `_file_find` call to the master

[vzhestkov]

What does this PR do?

This PR is intended to improve the performance in the large scale deployments as there is a useless call to get stats of the syncronized files which is not used. Seem it's a leftover of removing the code with https://github.com/saltstack/salt/pull/40609 due to https://github.com/advisories/GHSA-xcx4-5wq7-g5g7 introduced with https://github.com/saltstack/salt/commit/73a156d28cafd45dcc6c2aac9f1ac3ad905695e3 (https://github.com/saltstack/salt/pull/34807 ???)
