csky: add missing brackets in a macro for tlb.h
As an earlier patch made the macro argument more complicated, compilation
now fails with:
In file included from mm/madvise.c:30:
mm/madvise.c: In function 'madvise_free_single_vma':
arch/csky/include/asm/tlb.h:11:11: error:
invalid type argument of '->' (have 'struct mmu_gather')
Link: https://lore.kernel.org/r/20190901193601.GB5208@mellanox.com
Fixes: 923bfc561e75 ("pagewalk: separate function pointers from iterator data")
