RDMA/bnxt_re: Fix the max msix vectors macro

RDMA/bnxt_re: Fix the max msix vectors macro

bnxt_re no longer decide the number of MSI-x vectors used by itself.
Its decided by bnxt_en now. So when bnxt_en changes this value, system
crash is seen.

Depend on the max value reported by bnxt_en instead of using the its own macros.
