commit 056b93566a35 ("mm/vmalloc: warn only once when vmalloc
detect invalid gfp flags") modify the function call from WARN to WARN_ONCE.

WARN_ONCE input parameter format error, missing ',' tag.
Resulting in the following compilation errors:

mm/vmalloc.c:3940:19: error: expected ‘)’ before ‘invalid_mask’
 3940 |                   invalid_mask, &invalid_mask, flags, &flags);

After adding the "," tag, the compilation passed.
