mdadm: fix ptest hang

Before commit[80d17497b7 mdadm: improve the run-ptest],
the mdadm ptest just run some tests without
"--keep-going" option. After the option added in
commit 80d17497b7, all test cases have chance to
be called.

But the logic in mdadm upstream commit
[e2a8e9d tests: wait for complete rebuild in integrity checks]
will make the test enter infinite loop especially in
qemu env as commit e2a8e9d update the logic from
"check wait" to "check state 'U*'" for testcase
tests/01r5integ and tests/01raid6integ. Considering all
other cases still use "check wait" logic, so revert e2a8e9d
to make tests/01r5integ and tests/01raid6integ also use
"check wait" logic to avoid the infinite loop.

+Subject: [PATCH] Revert "tests: wait for complete rebuild in integrity checks"
+
+This reverts commit e2a8e9dcf67a28bc722fa5ab2c49b0bc452d4d74
+as the logic "check state 'U*'" will make the test enters
+infinite loop especially in qemu env, so revert it to
+use the previous logic "check wait" which also used
+commonly by other tests such as tests/02r5grow, tests/07revert-grow
+and etc.
