Ben Gras 30804b9ed7 thanks to tomas: fix for level0() race condition - global variable can
be used concurrently.  pass the function in eax instead; this gets rid
of the global variable.  also execute the function directly if we're
already trapped into the kernel.

revert of u32_t endpoint_t to int (some code assumes endpoints are
negative for negative slot numbers).
