Use umode_t as parameter type for sel_make_inode(), which assigns the
value to the member i_mode of struct inode.

Use identical and unsigned types for loop iterators.

v3:
  - drop leftover declaration in init-clauses of for loops
  - use unsigned int instead of u32 for loop iterator with loop bounds
    known at compile time to be small (<100)
v2: avoid declarations in init-clauses of for loops

Merged into selinux/next, thanks.
