Staging: android: ashmem.c: Convert macros page_range_{subsumes/subsumed_by/in}_range to static inline function

Convert macros page_range_{subsumes/subsumed_by/in}_range to static
inline function as static inline functions are preferred over macros.
The change can be done as the arguments at all call sites have the same
type. Also, all three macro have same type of arguments and return
values so they can converted using a common semantic patch.
