[PATCH 12/12] ipc/util.c: update return value of ipc_getref from int to bool

ipc_getref has still a return value of type "int", matching the atomic_t interface of atomic_inc_not_zero()/atomic_add_unless(). ipc_getref now uses refcount_inc_not_zero, which has a return value of type "bool". Therefore: Update the return code to avoid implicit conversions. Signed-off-by:
