Block creation of the imsm volume when given size is smaller than 1M and
print appropriate message.
Commit b53bfba6119d3f6f56eb9e10e5a59da6901af159
(imsm: use rounded size for metadata initialization) introduces issue with
rounding volume sizes smaller than 1M to 0. There is an inconsistency when
size smaller than 1M was given depends of what we give as target device:
1) When block devices was given created volume has maximum available size.
2) When container symlink was given created volume has size 0. Additionally
it causes below call trace:

mdadm assumes that blocks_per_member value is equal to num_data_stripes *
blocks_per_stripe but it is not true. For IMSM arrays created in OROM
NUM_BLOCKS_DIRTY_STRIPE_REGION sectors are added up to this value. Because
of this mdadm shows invalid size of arrays created in OROM and to fix this
we need to use array size calculation based on num data stripes and blocks
per stripe.

In almost every place where imsm_num_data_members is called there is
already existing map so it can be used it to avoid mistake when specifying
map for imsm_num_data_members.

Due to compatibility to the newest OROM, imsm reserved space has to be
expanded to 4MB.

* use-tempnode-not-devnode.patch: change udev rules file to use
$tempnode which works both on wheezy and jessie udev, instead
of $devnode which only works in jessie. At this stage it is
better to make rules file compatible with old version instead
of adding versioned dependency. Should be removed for jessie+1.
