libmemtrack: check return value for getMemory()

libmemtrack does not report an error when the binderized memtrack
service dies during a call to getMemory, so a crash in the memtrack
service can result in the calling process (e.g. system_server)
crashing as well. Add an error check to avoid this problem.

Bug: 35728498
Test: adb shell kill -9 $(adb shell pidof android.hardware.memtrack@1.0-service)
