[PATCH nft] intervals: fix compilation --with-mini-gmp

[Pablo Neira Ayuso <pablo@netfilter.org>]

Use pr_gmp_debug() instead to compile with minigmp.

intervals.c: In function ‘set_delete’:
intervals.c:489:25: warning: implicit declaration of function ‘gmp_printf’; did you mean ‘gmp_vfprintf’? [-Wimplicit-function-declaration]
  489 |                         gmp_printf("remove: [%Zx-%Zx]\n",
      |                         ^~~~~~~~~~
      |                         gmp_vfprintf
