ide: set hwif->expiry prior to calling [__]ide_set_handler()
* Set hwif->expiry prior to calling [__]ide_set_handler()
and drop 'expiry' argument.
* Set hwif->expiry to NULL in ide_{timer_expiry,intr}()
and remove 'hwif->expiry = NULL' assignments.
There should be no functional changes caused by this patch.
