net/mlx5: E-Switch, Get reg_c1 value on miss
The HW model implicitly decapsulates tunnels on chain 0 and sets reg_c1
with the mapped tunnel id. On miss, the packet does not have the outer
header and the driver restores the tunnel information from the tunnel id.
Getting reg_c1 value in software requires enabling reg_c1 loopback and
copying reg_c1 to reg_b. reg_b comes up on CQE as cqe->imm_inval_pkey.
Use the reg_c0 restoration rules to also copy reg_c1 to reg_B.
