From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

1. refactor stats allocation code to new routine
2. check for extended statistics support depends on "hwrm_spec_code"
   which is set in bnxt_hwrm_ver_get called later. Hence we were never
   querying extended port stats as flags field was not updated. Fixed
   this by moving the stats allocation after the call to
   bnxt_hwrm_ver_get.
3. we were incorrectly passing the host address used for port
   statistics to PORT_QSTATS_EXT command. Fixed this by passing the
   correct extended stats address.

Fixes: f55e12f33416 ("net/bnxt: support extended port counters")

You could use the PCI_PRI_FMT definition from rte_pci.h here.
