Shaun Ruffell 104745a775 wctc4xxp: Ensure the descriptors are zeroed out on start.
If system conditions prevent the card from loading the firmware without
touching all the descriptors in the ring, it's possible for
wctc4xxp_cleanup_descriptor_ring to attempt cleanup of a command that was never
submitted resulting in the following BUG.

  wctc4xxp 0000:02:0a.0: Failed to load firmware.
