bnxt_en: Fix ring checking logic on 57500 chips.

In bnxt_hwrm_check_pf_rings(), add the proper flag to test the NQ
resources.  Without the proper flag, the firmware will change
the NQ resource allocation and remap the IRQ, causing missing
IRQs.  This issue shows up when adding MQPRIO TX queues, for example.

Fixes: 9d188d80012d ("bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.")
