do_sys_poll: simplify playing with on-stack data
Cleanup. Lessens both the source and compiled code (100 bytes) and imho makes
the code much more understandable.
With this patch "struct poll_list *head" always points to on-stack stack_pps,
so we can remove all "is it on-stack" and "was it initialized" checks.
Also, move poll_initwait/poll_freewait and -EINTR detection closer to the
do_poll()'s callsite.
