Subject: [PATCH] scripts/decode_stacktrace.sh: remove trailing space

decode_stacktrace.sh adds a trailing space at the end of the decoded
stack if the module is not set (in most of the lines), which makes the
some lines of the stack having trailing space and some others not.

Do not add an extra space at the end of the line if module is not set,
adding consistency in output formatting.
