drivers: staging: zcache: fix compile error

Because 'ramster_debugfs_init' is not defined if !CONFIG_DEBUG_FS, there is compile error: $ make drivers/staging/zcache/ staging/zcache/ramster/ramster.c: In function ‘ramster_init’: staging/zcache/ramster/ramster.c:981:2: error: implicit declaration of function ‘ramster_debugfs_init’ [-Werror=implicit-function-declaration] This patch fix it and reduce some #ifdef CONFIG_DEBUG_FS in .c files the same way.
