Fix USB storage hang on command abort

Okay, I found the cause of the hang.  It is a simple bug in the USB
scatter-gather library, caused by changes added in response to the S-G
chaining modification.

This patch (as1125) fixes a bug in the USB scatter-gather library.
Early exit from the S-G initialization loop does not reset the count of
outstanding URBs.
