Stop using configuration parameter to set max number of queues and

net/vmxnet3: reallocate shared memzone on re-config

When adding a DPDK port to ovs-vswitchd with DPDK, the vmxnet3 device
fails to activate due to mismatched magic number.  This failure causes
following operations to run: start the port, stop the port,
reconfigure and re-start the port.

During reconfigure, if there is an existing memzone, driver will reuse
it. But reconfigure may request different number of Tx/Rx queues.
This results in a memzone with wrong size and potential invalid memory
access.

To fix this, free the memzone if found and reserve a new one.
