Ian Rogers 37862d6fdc perf dso: Use container_of() to avoid a pointer in 'struct dso_data' 
The dso pointer in 'struct dso_data' is necessary for reference count
checking to account for the dso_data forming a global list of open dso's
with references to the dso.

The dso pointer also allows for the indirection that reference count
checking needs. Outside of reference count checking the indirection
isn't needed and container_of() is more efficient and saves space.

The reference count won't be increased by placing items onto the global
list, matching how things were before the reference count checking
change, but we assert the dso is in dsos holding it live (and that the
set of open dsos is a subset of all dsos for the machine).

Update the DSO data tests so that they use a dsos struct to make the
invariant true.
