Coverity complains of an uninitialized variable.

CID 120847 (#1 of 1): Uninitialized scalar variable (UNINIT)
3. uninit_use_in_call: Using uninitialized value *sw_platform_str when calling qed_dump_str_param. [show details]
1344        offset += qed_dump_str_param(dump_buf + offset,
1345                                     dump, "sw-platform", sw_platform_str);

Fix this by removing dead code that references sw_platform_str.

Fixes: 6c95dd8f0aa1d ("qed: Update debug related changes")
