The extended complex NRM2 tests can compare an expected +Inf norm with a computed +Inf norm. The relative-error path then evaluates Inf - Inf, producing NaN and reporting a spurious failure. Treat exactly equal results as zero test ratio before computing the relative difference. This matches the existing SNRM2 and DNRM2 test logic. Fixes Reference-LAPACK#1047.

Description
The extended complex NRM2 tests can compare an expected +Inf norm with a computed +Inf norm. The relative-error path then evaluates Inf - Inf, producing NaN and reporting a spurious failure.
Treat exactly equal results as zero test ratio before computing the relative difference. This matches the existing SNRM2 and DNRM2 test logic.
Fixes #1047.
