Subject: [md] dm raid45: don't clear the suspend flag on recovery

O-Subject: [RHEL 5.4 PATCH] dm: raid45 target doesn't create parity as expected by dmraid (isw)

RHEL5.4 device mapper: raid45 target

"Re: [RHEL 5.4 PATCH] dm: raid45 target doesn't create parity as expected by dmraid (isw)

that the RAID target wouldn't restart a partial recovery on resume,
because it clears the related flag on suspend of the mapped device.

The attached one liner, which didn't make it into my previous bz499406
related patch for some reason, fixes the issue.

Please ACK.
