ANDROID: Fix sched/core.o 'if' clause build error

A conditional tracepoint originally introduced in
commit 6a878921 ("ANDROID: sched: move
blocked reason trace point to cover all class") was not indented to be
in-line with the other relevant code blocks after a scoped_guard was
placed around them in commit 857d315f
("sched: Simplify ttwu()"). This didn't cause any issues until an #ifdef
in between the conditional and the subsequent line was removed in
commit d0a0a055 ("sched/smp: Use the SMP
version of try_to_wake_up()").

Indent the conditional to prevent the following kernelci build error:

kernel/sched/core.c: In function ‘try_to_wake_up’:
kernel/sched/core.c:4319:9: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
