build: Fix build when using -fno-inline

struct task_slice.migrated is not initialised by this function, and
subsequently returned by value, leading to the error:

sched_sedf.c: In function ?sedf_do_extra_schedule?:
sched_sedf.c:711: error: ?ret.migrated? may be used uninitialised in
this function

for both gcc 4.1.2 and 4.4.3 (which are the two I have easily to hand)
when combined with the -fno-inline compile option.
