mm/cma: add 'available count' and 'total count' to trace_cma_alloc_start
This makes cma info more intuitive during debugging.
Show up in the trace as:
279.814717: cma_alloc_start: name=reserved request_count=4 available_count=8096 total_count=8192 align=0
309.790580: cma_alloc_start: name=reserved request_count=4 available_count=8092 total_count=8192 align=0
317.046609: cma_alloc_start: name=reserved request_count=4 available_count=8088 total_count=8192 align=0
