mdadm.8: move description of --add under Grow mode 

It is supposed to be under Grow mode. Since Create/Build/Grow modes
use common options and '-a' is already used for '--auto' in Create/
Build modes, describe it to avoid confusion.

This option can be used in Grow mode in two cases.
If the target array is a Linear array, then
.B \-\-add
can be used to add one or more devices to the array. They
are simply catenated on to the end of the array. Once added, the
devices cannot be removed.
If the
.B \-\-raid\-disks
option is being used to increase the number of devices in an array,
then
.B \-\-add
can be used to add some extra devices to be included in the array.
In most cases this is not needed as the extra devices can be added as
spares first, and then the number of raid-disks can be changed.
However for RAID0, it is not possible to add spares. So to increase
the number of devices in a RAID0, it is necessary to set the new
number of devices, and to add the new devices, in the same command.
