USB: EHCI: fix divide-by-zero bug

commit 372dd6e8ed924e876f3beb598721e813ad7fa323 upstream.

This patch (as1164) fixes a bug in the EHCI scheduler.  The interval
value it uses is already in linear format, not logarithmically coded.
The existing code can sometimes crash the system by trying to divide
by zero.
