Ignore "non-existing" errors when getDirectorySize calculates the size (#28276) 

The git command may operate the git directory (add/remove) files in any
time.

So when the code iterates the directory, some files may disappear during
the "walk". All "IsNotExist" errors should be ignored.

Fix #26765
