RDMA/i40iw: Fix error unwinding when i40iw_hmc_sd_one fails

When i40iw_hmc_sd_one fails, chunk is freed without the deletion of chunk
entry in the PBLE info list.

Fix it by adding the chunk entry to the PBLE info list only after
successful addition of SD in i40iw_hmc_sd_one.

This fixes a static checker warning reported here:
