perf: Shrink the size of the recursion counter.
There are four recursion counter, one for each context. The type of the
counter is `int' but the counter is used as `bool' since it is only
incremented if zero.
The main goal here is to shrink the whole struct into 32bit int which
can later be added task_struct into an existing hole.
Reduce the type of the recursion counter to an unsigned char, keep the
increment/ decrement operation.
