Subject: [PATCH] Manage: Remove the legacy code for md driver prior to 0.90.03
Git-commit: 1cc3965d48deb0fb3e0657159c608ffb124643c1
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348

Previous re-add operation only calls ioctl(HOT_ADD_DISK) for array without
metadata(e.g. mdadm -B/--build) when md driver is less than 0.90.02, but
commit 091e8e6 breaks the logic and current re-add operation can call
ioctl(HOT_ADD_DISK) even if md driver is 0.90.03.

This issue is reproduced by 05r1-re-add-nosuper:
