x86/platform/olpc: Remove unused variable 'len' in olpc_dt_compatible_match()

Browse Source 
The following build warning highlights some unused code:

  arch/x86/platform/olpc/olpc_dt.c: In function ‘olpc_dt_compatible_match’:
  arch/x86/platform/olpc/olpc_dt.c:222:12: warning: variable ‘len’ set but not used [-Wunused-but-set-variable]

The compiler is right, the local variable 'len' is set but never used,
so remove it.
