sched_ext: Rename scx_local_or_reject_dsq() to scx_resolve_local_dsq()

Browse Source 
The following rescue execution addition gives the function a third possible
destination, making a name that enumerates the outcomes a poor fit. Rename
to the destination-neutral scx_resolve_local_dsq(). No functional changes.
