From: Jesse Millan <jessem@cs.pdx.edu>

This patch eliminates the GCC4 warning on the x86_64 platform:

kernel/sched.c:1824: warning: control may reach end of non-void function
'sched_find_first_bit' being inlined.

The change follows the lead of others, i.e.  it is guaranteed that at least
one of b[0], b[1], or b[2] will have a bit set and evaluate to true.  That
being said, GCC4.0.0 notices that the code flow does not return anything if
b[0], b[1] and b[2] are not true.  Since we know better, if it's not b[0] or
b[1], it has to be b[2].
