Subject: RDMA/bnxt_re: Update missing hsi data structures
Patch-mainline: v5.8-rc1
Git-commit: c78671a4e65ae0b2e639ea61b4c65842c4200f2d
References: jsc#SLE-15076

Adding fast path support data structure into hardware HSI. These
structures are header only definition of RQE/SRQE/SQE. This is to help
calculating the size of hardware wqe size.
