nedmalloc: avoid compiler warning about unused value
Cast the evaluated value of the macro INITIAL_LOCK to void to instruct
the compiler that we're not interested in said value nor the following
warning:
In file included from compat/nedmalloc/nedmalloc.c:63:
compat/nedmalloc/malloc.c.h: In function ‘init_user_mstate’:
compat/nedmalloc/malloc.c.h:1706:62: error: right-hand operand of comma expression has no effect [-Werror=unused-value]
1706 | #define INITIAL_LOCK(sl) (memset(sl, 0, sizeof(MLOCK_T)), 0)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
compat/nedmalloc/malloc.c.h:5020:3: note: in expansion of macro ‘INITIAL_LOCK’
5020 | INITIAL_LOCK(&m->mutex);
| ^~~~~~~~~~~~
