Brian Behlendorf a32494d22a Fix suspend Godfather I/Os io_reexecute bits ...

After resuming a pool the godfather zio could have both the
ZIO_REEXECUTE_NOW and ZIO_REEXECUTE_SUSPEND bits set.  This
can occur if some child zios set ZIO_REEXECUTE_NOW while
other set ZIO_REEXECUTE_SUSPEND.  The godfather zio can
inherit both flags in zio_notify_parent().

The child zios which assigned the ZIO_REEXECUTE_SUSPEND flag
will be removed from the godfather's child list and added to
the spa->spa_suspend_zio_root child list.   While child zios
with the ZIO_REEXECUTE_NOW bit set remain being monitored
by the godfather zio.

When the godfather zio executes zio_done() the presence of
the ZIO_REEXECUTE_SUSPEND bit results in all io_reexecute
being cleared.  These child zios will then not be re-executed
and instead will be destroyed and lost.

The most straight forward way to address this situation is
to only clear the ZIO_REEXECUTE_SUSPEND bit and leave the
ZIO_REEXECUTE_NOW bit set.
