bnxt_en: Fix AGG ring check logic in bnxt_check_rings()
_bnxt_get_max_rings() that is invoked in bnxt_check_rings() already
accounts for the AGG ring(s) and gives a max value based on that.
Increasing for AGG rings before calling _bnxt_get_max_rings() will
result in checking for twice the number of rings than required and
it can fail. Fix it by adjusting for AGG rings after calling
_bnxt_get_max_rings().
Fixes: f5b29c6afe36 ("bnxt_en: Add helper to get the number of CP rings required for TX rings")
