Revert "ANDROID: fs: FS tracepoints to track IO."

5.18-rc1 has many merge issues and the block io path has been rewritten,
so the tracepoints added here do not work properly anymore (and break
the build.)

If this is really still needed (hint, I strongly doubt it), it can be
redesigned and added back after 5.18-rc1 is released.
