Subject: [Backport dd854e4b5b12] src: Remove unnecessary condition
 checking from ntfs_file_read_iter

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
	src/file.c:803 ntfs_file_read_iter()
	warn: unused return: count = iov_iter_count()
