This fixes a performance issue when pc & gpt partmap iterators
didn't abort iteration even after our hook found what it was
looking for (often causing expensive probes of non-existant drives).
Some callers relied on previous buggy behaviour, since they would
rise an error when their own hooks caused early abortion of its
iteration.

early abortion of pc_partition_map_iterate().
* partmap/gpt.c (gpt_partition_map_iterate): Abort parent iteration
when hook requests it, independently of grub_errno.

early abortion of gpt_partition_map_iterate().

when hook requests it, independently of grub_errno. Do not fail when
part_map_iterate_hook() caused early abortion of p->iterate().

grub_dprintf() arguments to fix warnings.
* disk/raid.c (grub_raid_scan_device): Add a pair of sanity checks for

additionally, when such disk contains a memberlist() struct member,
once for each disk that is contained in the structure returned by
memberlist().
* disk/raid.c (grub_raid_scan_device): Check for
`array->device[sb.this_disk.number]' rather than for
`array->device[sb.this_disk.number]->name', since the latter is not
garanteed to be accessible.
* include/grub/raid.h (struct grub_raid_array): Change type of `device'
to a grub_disk_t array.
* disk/raid.c (grub_raid_read): Replace `device[x].disk' accesses with
`device[x]'.
