efi_loader: capsule: fix SIZEOF_MISMATCH warning

CID 316361 says:
> Passing argument "count * 8UL /* sizeof (*files) */" to
> function "dlmalloc" and then casting the return value to "u16 **" is
> suspicious. In this particular case "sizeof (u16 **)" happens to be equal
> to "sizeof (u16 *)", but this is not a portable assumption.
