Fix an erroneous logging format string and pylint pragma

[bradlarsen]

Description

This pull request fixes an incorrect logging format string and a pylint pragma that incorrectly disables its warning it.

I noticed this issue when using TorchServe's profiling mechanism via the ENABLE_TORCH_PROFILER=1 environment variable, which resulted in surprising non-fatal stack traces. For example:
