rhashtable: Add immediate rehash during insertion
This patch reintroduces immediate rehash during insertion. If we find during insertion that the table is full or the chain length exceeds a set limit (currently 16 but may be disabled with insecure_elasticity) then we will force an immediate rehash. The rehash will contain an expansion if the table utilisation exceeds 75%. If this rehash fails then the insertion will fail. Otherwise the insertion will be reattempted in the new hash table.
