scsi: lpfc: Fix lpfc_io_buf resource leak in lpfc_get_scsi_buf_s4 error path
If a call to lpfc_get_cmd_rsp_buf_per_hdwq returns NULL (memory allocation
failure), a previously allocated lpfc_io_buf resource is leaked.
Fix by releasing the lpfc_io_buf resource in the failure path.
Fixes: d79c9e9d4b3d ("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")
