bnxt_en: Set bp->max_tpa according to what the FW supports

Browse Source 
Fix the logic to set bp->max_tpa no higher than what the FW supports.
On P5 chips, some older FW sets max_tpa very low so we override it to
prevent performance regressions with the older FW.

Fixes: 79632e9ba3 ("bnxt_en: Expand bnxt_tpa_info struct to support 57500 chips.")
