Staging: android: ashmem.c: Redefine macros as static inline functions

Convert macros page_in_range and range_before_page into static inline
functions 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, both the macros have same type of arguments and return
values.
Done using coccinelle:

@r@
identifier f;
expression e;
@@
#define f(...) e

@r1@
identifier r.f;
identifier range,page;
expression r.e;
@@
- #define f(range,page) e
+ static inline int f(struct ashmem_range *range, size_t page)
+ {
+	return e;
+ }
