libspl: cast to uintptr_t instead of !!ing

This led to these two warning types:
  debug.h:139:67: warning: the address of ‘ARC_anon’
  will always evaluate as ‘true’ [-Waddress]
    139 | #define ASSERT3P(x, y, z)
              ((void) sizeof (!!(x)), (void) sizeof (!!(z)))
        |                                               ^
  arc.c:1591:2: note: in expansion of macro ‘ASSERT3P’
   1591 |  ASSERT3P(hdr->b_l1hdr.b_state, ==, arc_anon);
        |  ^~~~~~~~
and
  arc.h:66:44: warning: ‘<<’ in boolean context,
  did you mean ‘<’? [-Wint-in-bool-context]
     66 | #define HDR_GET_LSIZE(hdr)
              ((hdr)->b_lsize << SPA_MINBLOCKSHIFT)

  arc.c:1760:12: note: in expansion of macro ‘HDR_GET_LSIZE’
   1760 |   ASSERT3U(HDR_GET_LSIZE(hdr), !=, 0);
