checkpatch: fix regressions in "fix handling of leading spaces"
The patch "checkpatch: fix handling of leading spaces" added checks for
leading spaces on lines, but this introduces regressions. Firstly it does
not correctly detect when we are in a comment. Secondly it does not allow
for preprocessor command spacing. Finally it does not allow for label
indentation which is required to be less than one tab. Fix these up:
