if ore_write() fails, we would unlock the pages of pcol, which is now empty, rather than pcol_copy which owns the pages when ore_write() is called. this means that no pages will actually be unlocked (pcol.nr_pages == 0) and the writing process (more accurately, the syncing process) will hang waiting for a writeback notification that never comes. moreover, if ore_write() fails, pcol_free() is called for pcol, whereas pcol_copy is the object owning the ore_io_state, thus leaking the ore_io_state.
