Remove uninitialized use of new_crr in erl_alloc_util

When the offending code is reached, new_crr is either uninitalized or
have been set to NULL. This patch removes the following warning:

beam/erl_alloc_util.c:3510:6: warning: variable 'new_crr' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (!(flags & CFLG_FORCE_MSEG)) {
            ^~~~~~~~~~~~~~~~~~~~~~~~~~
beam/erl_alloc_util.c:3567:23: note: uninitialized use occurs here
        DEBUG_SAVE_ALIGNMENT(new_crr);
                             ^~~~~~~

beam/erl_alloc_util.c:3510:2: note: remove the 'if' if its condition is always true
        if (!(flags & CFLG_FORCE_MSEG)) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
beam/erl_alloc_util.c:3438:23: note: initialize the variable 'new_crr' to silence this warning
    Carrier_t *new_crr, *old_crr;
                      ^
                       = NULL
