xfs: move xfs_rtget_summary to xfs_rtbitmap.c

Source kernel commit: c2adcfa31ff606264fab6e69129d6d45c9ddb7cb

xfs_rtmodify_summary_int is only used inside xfs_rtbitmap.c and to
implement xfs_rtget_summary.  Move xfs_rtget_summary to xfs_rtbitmap.c
as the exported API and mark xfs_rtmodify_summary_int static.
