PATCH 1/1 musb_host: compare status for negative error values

From: Márton Németh <[email protected]>

Variable d is a struct usb_iso_packet_descriptor. The status filed is usually negative when an error happens.

This was not tested at all! I just found this while I was browsing the code and it looked like a typo. Please verify and test it before aplying this patch. If I was wrong, sorry about that.
