handle exception for psutil.NoSuchProcess along with psutil.AccessDenied

[yeggor]

Hi. I've noticed that there can be a condition where process will be killed between

memory_profiler/memory_profiler.py

Line 134 in 025929f

process = psutil.Process(pid)

and

memory_profiler/memory_profiler.py

Line 140 in 025929f

mem = getattr(process, meminfo_attr)()[0] / _TWO_20

In this case, we get an exception psutil.NoSuchProcess: process no longer exists (pid=...), that we have to handle the same way as it's done here:

memory_profiler/memory_profiler.py

Line 112 in 025929f

except (psutil.NoSuchProcess, psutil.AccessDenied):
