When adding REMOVED_FLAG to the pointers in the rculfhash
implementation, retype the generic pointer to unsigned long to fix the
following compiler error:

rculfhash.c:1201:2: error: address argument to atomic operation must be a 
pointer to integer ('struct cds_lfht_node **' invalid)
       uatomic_or(&node->next, REMOVED_FLAG);
       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../include/urcu/uatomic.h:60:8: note: expanded from macro 'uatomic_or'
       (void)__atomic_or_fetch((addr), (mask), __ATOMIC_RELAXED)
             ^                 ~~~~~~
rculfhash.c:1444:3: error: address argument to atomic operation must be a 
pointer to integer ('struct cds_lfht_node **' invalid)
               uatomic_or(&fini_bucket->next, REMOVED_FLAG);
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../include/urcu/uatomic.h:60:8: note: expanded from macro 'uatomic_or'
       (void)__atomic_or_fetch((addr), (mask), __ATOMIC_RELAXED)
             ^                 ~~~~~~

This was not a problem before because the way the uatomic_or was
implemented, but now we directly pass the addr to __atomic_or_fetch()
and the compiler doesn't like the implicit conversion from pointer to
pointer to integer.
