mm/slab_common.c: make calculate_alignment() static
calculate_alignment() function is only used inside slab_common.c. So
make it static and let the compiler do more optimizations.
After this patch there's a small improvement in text and data size.
$ gcc --version
gcc (GCC) 7.2.1 20171128
Before:
text data bss dec hex filename
9890457 3828702 1212364 14931523 e3d643 vmlinux
After:
text data bss dec hex filename
9890437 3828670 1212364 14931471 e3d60f vmlinux
Also I fixed a style problem reported by checkpatch.
