mm/cma: fix placement of trace_cma_alloc_start/finish
The current placement of trace_cma_alloc_start/finish misses the fail
cases: !cma || !cma->count || !cma->bitmap.
trace_cma_alloc_finish is also not emitted for the failure case
where bitmap_count > bitmap_maxno.
Fix these missed cases by moving the start event before the failure
checks and moving the finish event to the out label.
