bnxt_en: Reduce BNXT_MSIX_VEC_MAX value to supported CQs per PF.
[ Upstream commit 9e68cb0359b20f99c7b070f1d3305e5e0a9fae6d ]
Broadcom adapters support only maximum of 512 CQs per PF. If user sets
MSIx vectors more than supported CQs, firmware is setting incorrect value
for msix_vec_per_pf_max parameter. Fix it by reducing the BNXT_MSIX_VEC_MAX
value to 512, even though the maximum # of MSIx vectors supported by adapter
are 1280.
Fixes: f399e8497826 ("bnxt_en: Use msix_vec_per_pf_max and msix_vec_per_pf_min devlink params.")
