pnfs-obj: Remove redundant EOF from objlayout_io_state
The EOF calculation was done on .read_pagelist(), cached in objlayout_io_state->eof, and set in objlayout_read_done() into nfs_read_data->res.eof. So set it directly into nfs_read_data->res.eof and avoid the extra member. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
