[malloc] Guard against unsigned integer overflow
Commit f3fbb5f ("[malloc] Avoid integer overflow for excessively large
memory allocations") fixed signed integer overflow issues caused by
the use of ssize_t, but did not guard against unsigned integer
overflow.
Add explicit checks for unsigned integer overflow where needed. As a
side bonus, erroneous calls to malloc_dma() with an (illegal) size of
zero will now fail cleanly.
