kernel/{sched, smp}.c: fix static decl prior to struct declaration
According to C99 6.9.2p3, any declaration "static struct foo my_foo;"
must follow the definition of struct foo.
Apparently, gcc's lack of warning is a bug.
v2:
- fix ifdef imbalance, by moving entire USER_SCHED code block
- indent cpp directives, to indicate nesting
[ Impact: cleanup ]
