Yufen Yu 67f8d96a2c md: add mddev->pers to avoid potential NULL pointer dereference ...

commit ee37e62191 upstream.

When doing re-add, we need to ensure rdev->mddev->pers is not NULL,
which can avoid potential NULL pointer derefence in fallowing
add_bound_rdev().

Fixes: a6da4ef85c ("md: re-add a failed disk")
