Lukas Sismis 214e47bea1 dpdk: move to native queue-sized mempools 
As a legacy from Suricata 7, mempool size was kept even internally
as a global size. Since in Suricata 8, mempool allocation moved to
per queue model, it makes sense to calculate the correct size right
when loading the configuration.

The previous implementation misscalculated in some scenarios the size
of the mempool which prevented Suricata starting successfully.
This happened, e.g. when there were 32k RX descriptors and 64 TX descs.
The resulting mempool was incorrectly deduced as 32767 (2^n-1), which
didn't even hold all RX descriptors. Instead, it should result to 65535.
