We've already set the variable 'i' 's initial value before using it,
thus remove redundant previous assignment of variable 'i'.

Matthew's patch series "Refactor generic_file_buffered_read "
(https://lkml.kernel.org/r/20210122160140.223228-1-willy@infradead.org)
changes all this code - I dont think the patch is relevant after that,
so I'll skip it.
