SCSI: ARM: make fas216_dumpinfo function conditional

The fas216_dumpinfo function is only used by __fas216_checkmagic,
which is conditionally compiled, so we should put both functions
inside of the same #ifdef.

Without this patch, building rpc_defconfig results in:

drivers/scsi/arm/fas216.c:182:13: warning: 'fas216_dumpinfo' defined but not used [-Wunused-function]
