Browse Source 
compile error:
  CC [M]  .../lib/librte_eal/linuxapp/kni/kni_misc.o

error: unused variable ‘knet’

For kernel versions < v3.1 mutex_destroy() is a macro and does nothing,
this cause an unused variable warning for knet which used in the
mutex_destroy()

mutex_destroy() converted into static inline function with commit:
Linux: 4582c0a4866e ("mutex: Make mutex_destroy() an inline function")

To fix the warning unused attribute added to the knet variable.

Fixes: 93a298b34e1b ("kni: support core id parameter in single threaded mode")
