Subject: Fix segfault on assembly on amd64 with v1 superblocks
X-Git-Tag: mdadm-2.6.4~7

Fix segfault on assembly on amd64 with v1 superblocks

Commit a40b4fe introduced a temporary supertype variable tst, instead of
manipulating st directly. However, it was forgotton to pass &tst into the
recursive load_super1 call, causing an infinite recursion.
