md: remove CONFIG_MD_RAID_RESHAPE config option.
This was only needed when the code was experimental. Most of it is well tested now, so the option is no longer useful. Signed-off-by: NeilBrown <neilb@suse.de>

- bool "Support adding drives to a raid-5 array"
- depends on MD_RAID456
- default y
- ---help---
- A RAID-5 set can be expanded by adding extra drives. This
- requires "restriping" the array which means (almost) every
- block must be written to a different place.
-
- This option allows such restriping to be done while the array
- is online.
-
- You will need mdadm version 2.4.1 or later to use this
- feature safely. During the early stage of reshape there is
- a critical section where live data is being over-written. A
- crash during this time needs extra care for recovery. The
- newer mdadm takes a copy of the data in the critical section
- and will restore it, if necessary, after a crash.
-
- The mdadm usage is e.g.
- mdadm --grow /dev/md1 --raid-disks=6
- to grow '/dev/md1' to having 6 disks.
-
- Note: The array can only be expanded, not contracted.
- There should be enough spares already present to make the new
- array workable.
-
- If unsure, say Y.
