Subject: [PATCH v2] orangefs: move debug only code into debugfs.c file

The s_kmod_keyword_mask_map[] is only used in orangefs-debugfs.c and is
casing a number of warnings about it being defined and not used. Fix
this by moving it to remove a lot of:

 warning: ‘num_kmod_keyword_mask_map’ defined but not used [-Wunused-const-variable=]
