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:
------------------------------------------------
++ die 'resync or recovery is happening!'
++ echo -e '\n\tERROR: resync or recovery is happening! \n'
ERROR: resync or recovery is happening!
------------------------------------------------
Fixes: 091e8e6("Manage: Remove all references to md_get_version()")
