Critical: Memory Info Calculation Error due to Interchanged Variable Names

[Muhammed-Rahif]

I have been looking around why the system monitor of the ubuntu and stacer memory info are not same. There are more than one issues regarding this issue in this repo already (mentioned below).

The issue is caused by https://github.com/oguzhaninan/Stacer/blob/native/stacer-core/Info/memory_info.cpp#L32-L33 where the variable names are interchanged mistakenly. Which is later causes inacuracy for measuring memory usage.

For more understading:

Requesting change:

- sreclaimable = getValue(6);
- shmem = getValue(7);
+ shmem = getValue(6);
+ sreclaimable = getValue(7);

This also have impact on the next lines where the memory usage actually calculates.

And:
From my findings, fixing this will not make the ubuntu system monitor and stacer same on calculation. Maybe because when calculating memory usage, the ubuntu system monitor and stacer differs, more info: https://stackoverflow.com/a/41251290/14781260
