RDMA/i40iw: Fix error unwinding when i40iw_hmc_sd_one fails

[ Upstream commit 783a11bf2400e5d5c42a943c3083dc0330751842 ]

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:
