[PATCH] netfilter: nf_tables: Add __percpu annotation to *stats pointer in nf_tables_updchain()

[Uros Bizjak]

Compiling nf_tables_api.c results in several sparse warnings:

nf_tables_api.c:2740:23: warning: incorrect type in assignment (different address spaces)
nf_tables_api.c:2752:38: warning: incorrect type in assignment (different address spaces)
nf_tables_api.c:2798:21: warning: incorrect type in argument 1 (different address spaces)

Add __percpu annotation to *stats pointer to fix these warnings.

Found by GCC's named address space checks.

There were no changes in the resulting object files.
