[PATCH liburing v2 3/8] test/io_uring_setup: Remove unused functions

[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. Unused functions are found:

  io_uring_setup.c:22:14: error: unused function 'features_string' [-Werror,-Wunused-function]
  static char *features_string(struct io_uring_params *p)
               ^
  io_uring_setup.c:44:14: error: unused function 'flags_string' [-Werror,-Wunused-function]
  static char *flags_string(struct io_uring_params *p)
               ^
  io_uring_setup.c:83:15: error: unused function 'dump_resv' [-Werror,-Wunused-function]
  static char * dump_resv(struct io_uring_params *p)
                ^
  3 errors generated.
  make[1]: *** [Makefile:215: io_uring_setup.t] Error 1
  make[1]: *** Waiting for unfinished jobs....

Remove them.
