Jason Gunthorpe 4c7d6dcd36 RDMA/siw: Fix DEFINE_PER_CPU compilation when ARCH_NEEDS_WEAK_PER_CPU
The initializer for the variable cannot be inside the macro (and zero
initialization isn't needed anyhow).

include/linux/percpu-defs.h:92:33: warning: '__pcpu_unique_use_cnt' initialized and declared 'extern'
  extern __PCPU_DUMMY_ATTRS char __pcpu_unique_##name;  \
                                 ^~~~~~~~~~~~~~
include/linux/percpu-defs.h:115:2: note: in expansion of macro 'DEFINE_PER_CPU_SECTION'
  DEFINE_PER_CPU_SECTION(type, name, "")
  ^~~~~~~~~~~~~~~~~~~~~~
drivers/infiniband/sw/siw/siw_main.c:129:8: note: in expansion of macro 'DEFINE_PER_CPU'
 static DEFINE_PER_CPU(atomic_t, use_cnt = ATOMIC_INIT(0));
        ^~~~~~~~~~~~~~

Also the rules for PER_CPU require the variable names to be globally
unique, so prefix them with siw_
