Driver exports pacing stats only on GenP5 and P7 adapters. But while
parsing the pacing stats, driver has a check for "rdev->dbr_pacing".
This caused a trace when KASAN is enabled.
BUG: KASAN: slab-out-of-bounds in bnxt_re_get_hw_stats+0x2b6a/0x2e00 [bnxt_re]
Write of size 8 at addr ffff8885942a6340 by task modprobe/4809
Fixes: 8b6573ff3420 ("bnxt_re: Update the debug counters for doorbell pacing")
