Fixes file corruption issues when reading contents via ceph client.
Call netfs_reset_subreq_iter() to align subreq->io_iter before calling netfs_clear_unread() to clear tail, as subreq->io_iter count and subreq->transferred might not be aligned after incomplete I/O, having the subreq's NETFS_SREQ_CLEAR_TAIL set.
Based on ee4cdf7b ("netfs: Speed up buffered reading"), which introduces a fix for the issue in mainline.

Sending this patch in an attempt to backport the fix introduced by commit ee4cdf7b ("netfs: Speed up buffered reading"), which however can not be cherry picked for older kernels, as the patch is not independent from other commits and touches a lot of unrelated (to the fix) code.
We would much rather take the original series of commits, what exactly are they here?
thanks,
