xfs: handle NULL open_zone for merged ioends in xfs_ioend_put_open_zones

Browse Source 
In theory we could fail multiple ioends before an open zone was assigned
to them, and the iomap code could merge them.  Check for NULL not only
for the main ioend but also all merged ones on ->io_list to handle this
case.
