…buffer pool size calculation (sonic-net#1706)

To calculate the buffer pool size, we need to accumulate all reserved memory and than subtract the sum from total available memory. In the current implementation, one part hasn’t been added to reserved memory, which causes the buffer pool size larger than it should be.
To fix it, we need to add it to reserved memory.

- What I did
Fix buffer over subscription in the buffer pool calculation.

- How I verified it
Run regression and manual test

…et#1706)

- What I did
Remove redundant mellanox dumps now that Mellanox SAI is taking care of that.

- How I did it
Deleted the part related to mstdumps from the generate_script

- How to verify it
Run 'show techsupport' see we no have mstdump folder but the actual dump available under the saisdk dump
