RDMA/bnxt_re: Avoid sending the modify QP workaround for latest adapters

Browse Source 
[ Upstream commit 064c22408a73b9e945139b64614c534cbbefb591 ]

The workaround to modify the UD QP from RTS to RTS is required
only for older adapters. Issuing this for latest adapters can caus
some unexpected behavior. Fix it
