[PATCH] protect ide_cdrom_capacity by ifdef



The only call to ide_cdrom_capacity is in code protected by
CONFIG_PROC_FS, so when that is not enabled, the compiler complains:

 drivers/ide/ide-cd.c:3259: warning: `ide_cdrom_capacity' defined but not used

Here is a patch that fixes that.  It provides some space savings for
embedded systems that are not using procfs, as well:
