rdma: set correct CQE flags

CQE flags located in bits 16-31 at offset 0x1c should be defined as
actual numbers instead of indexes. Besides, L3 header type for IPv4 is
10(2 in decimal) and for IPv6 is 01(1 in decimal) according to CQE entry
fields description of page 120 in Mellanox Programmer Reference Manual.
(https://network.nvidia.com/files/doc-2020/ethernet-adapters-programming-manual.pdf)

Fixing this issue will lead to correct CQE flags printing for rdma-input
node when buffer trace is enabled.

Type: fix
