[Skiboot] [PATCH 1/1] buddy: Fix warnings when undefining BUDDY_DEBUG

[Ryan Grimm]

In simulation, hundreds of millions of cycles are chewed up in this code
path:

PC: 0x0000000030033450 -> <.bitmap_tst_bit>+0x18
LR: 0x000000003003347c -> <.buddy_check_alloc>+0x14
    0x0000000031c13b30 -> <_ebss>+0x1803b30
    0x000000003003351c -> <.buddy_check_alloc_down>+0x4c
    0x00000000300339c4 -> <.buddy_free>+0x7c
    0x0000000030033be8 -> <.buddy_create>+0xcc
    0x0000000030089bbc -> <.xive_init>+0xf0
    0x00000000300157cc -> <.main_cpu_entry>+0x8a0
    0x000000003000275c -> <boot_entry>+0x1bc

Undefining BUDDY_DEBUG saves 30+ minutes of wall clock time, so fix
the "warning: unused parameter" messages when compiling.
