roots: Fix an issue with volume_for_path().
The earlier commit in 2dfc1a38982c4052bb32bc7fc06edeadf3908fb9 unintentionally changed the behavior. It gives a different result when looking up non-existent mount points (e.g. /cache on marlin). The logic behind volume_for_path("/xyz") is unclear: - It's fine to return non-null value if it's called by ensure_path_mounted() before accessing that file "/xyz". (Just based on the function name, we're not actually having this case.) - It should return nullptr if the caller is interested in the existence of that particular mount point "/xyz". This CL renames the function to volume_for_mount_point(), which does an exact match by querying the given mount point from libfs_mgr. The former volume_for_path() has been moved down to function scope for serving ensure_path_mounted() only. Test: Build and boot into recovery on bullhead and marlin respectively. 'View recovery logs'. Test: 'Mount /system' Test: 'Apply update from ADB' Change-Id: I1a16390f57540cae08a2b8f3d439d17886975217
