[PATCH v2 1/6] Staging: rtl8192e: Refactored rtllib_modes

[Felix Schlepper]

The initial reason for looking at this code was an
issue raised by checkpatch.pl:

     $ ./scripts/checkpatch.pl --terse -f drivers/staging/rtl8192e/rtllib_wx.c
     CHECK: Please use a blank line after function/struct/union/enum
     declarations

The additional blank line above the struct/before the headers is
just cleaner.

However, as it turns out since there is no str formatting required
One can replace the error prone str + size struct with a char array.
The rest of this patch fixes the usecases.
