bnxt_en: fix LRO/GRO_HW features in ndo_fix_features callback

Browse Source 
[ Upstream commit 366c304741729e64d778c80555d9eb422cf5cc89 ]

LRO/GRO_HW should be disabled if there is an attached XDP program.
BNXT_FLAG_TPA is the current setting of the LRO/GRO_HW.  Using
BNXT_FLAG_TPA to disable LRO/GRO_HW will cause these features to be
permanently disabled once they are disabled.
