Fix inconsistence in the shared headroom pool initialization
Why I did it
During initialization, if SHP is enabled
the buffer pool sizes, xoff have initialized to 0, which means SHP is disabled
but the buffer profiles already indicate SHP
later on the buffer pool sizes are updated with off being non-zero
In case the orchagent starts handling buffer configuration between 2 and 3, it is inconsistent between buffer pools and profiles, which fails Mellanox SAI sanity check.
To avoid it, it indicates SHP enabled by setting a very small buffer pool and SHP sizes
