ppc: fix warnings from GCC 4.6.0

Compiling PPC with GCC 4.6.0 20100925 produced a few warnings:
../fs/hfs/block.c: In function 'reuse':
../fs/hfs/block.c:304:11: error: variable 'chain' set but not used [-Werror=unused-but-set-variable]
../fs/iso9660/iso9660_mount.c: In function 'iso9660_name':
../fs/iso9660/iso9660_mount.c:18:16: error: variable 'uh' set but not used [-Werror=unused-but-set-variable]

Fix the warnings by avoiding write-only variables.
