This simple patch puts two fixes into the blktap backend. The first is a change of busid from an unsigned short to a u32 so we can accommodate the new expanded format (which doesn''t fit into 16-bits). The second is a minor fix to signal_tapdisk(); while developing, if the tools happen to set up the tapfds wrong, you can get into a situation where the idx passed to signal_tapdisk() is NULL, causing a kernel OOPS. The fix for signal_tapdisk() just returns if the idx is negative, preventing the crash.
