[PATCH] cfg80211 debugfs: Cleanup some checkpatch issues

[Pichugin Dmitry]

This fixes the checkpatch.pl warnings:
* Macros should not use a trailing semicolon.
* Spaces required around that '='.
* Symbolic permissions 'S_IRUGO' are not preferred.
* Macro argument reuse 'buflen' - possible side-effects
