Functions normal_busy, handle_uv2_busy, uv_flush_send_and_wait and
find_another_by_swack are local to the source, so make them static
Fixes various smatch warnings, such as:
"symbol 'find_another_by_swack' was not declared. Should it be static?"
"symbol 'handle_uv2_busy' was not declared. Should it be static?"

In my opinion, there is no need to mark *normal_busy* static, remove it
directly.
the commit c5d35d399e68(x86/UV2: Work around BAU bug) add it to
handle_uv2_busy(), but the handle_uv2_busy() is rewritten now. the
normal_busy is unused, can be remove.
By the way, there are also an other function named
uv_bau_message_interrupt() can be remove.
Thanks,
dou.
