This check will be also performed in generic_file_read_iter() so we do
not want to check this two times in a row.
This was founded with Smatch
fs/ntfs3/file.c:803 ntfs_file_read_iter()
warn: unused return: count = iov_iter_count()

I cc Dan also because I am happy that I finally managed to install
Smack and straight away I found something with it. Thank you for
this great tool.
Next step is to integrate Smack to CI system. But will probanly take
a moment.
