If CONFIG_NET_HWBM is not set, then these stub functions in
<net/hwbm.h> should be declared static to avoid trying to
export them from any driver that includes this.
Fixes the following sparse warnings:
./include/net/hwbm.h:24:6: warning: symbol 'hwbm_buf_free' was not declared.
Should it be static?
./include/net/hwbm.h:25:5: warning: symbol 'hwbm_pool_refill' was not declared.
Should it be static?
./include/net/hwbm.h:26:5: warning: symbol 'hwbm_pool_add' was not declared.
Should it be static?
