[PATCH liburing v2 4/8] ucontext-cp: Remove an unused function

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

When marking all internal functions as static after an attempt to
integrate `-Wmissing-prototypes` flag. An unused function is found:

  ucontext-cp.c:71:12: error: ‘await_poll’ defined but not used [-Werror=unused-function]
     71 | static int await_poll(async_context *pctx, int fd, short poll_mask)
        |            ^~~~~~~~~~
  cc1: all warnings being treated as errors
  make[1]: *** [Makefile:36: ucontext-cp] Error 1

Remove it.
