[PATCH] rpmb: use IS_REACHABLE instead of IS_ENABLED

[Jens Wiklander]

Use the macro IS_REACHABLE instead of IS_ENABLED in <linux/rpmb.h> when
deciding if prototypes or stubbed static inline functions should be
provided. This fixes link errors when the calling code is builtin while
the RPMB subsystem is a module.
