kasan: update outdated comment
kmalloc_large() was renamed kmalloc_large_noprof() by commit 7bd230a26648
("mm/slab: enable slab allocation tagging for kmalloc and friends"), and
subsequently renamed __kmalloc_large_noprof() by commit a0a44d9175b3 ("mm,
slab: don't wrap internal functions with alloc_hooks()"), making it an
internal implementation detail.
Large kmalloc allocations are now performed through the public kmalloc()
interface directly, making the reference to KMALLOC_MAX_SIZE also stale
(KMALLOC_MAX_CACHE_SIZE would be more accurate). Remove the references to
kmalloc_large() and KMALLOC_MAX_SIZE, and rephrase the description for
large kmalloc allocations.
