fix crash/misbehavior from oob read in new dynamic tls installation
code introduced in commit 9d44b6460ab603487dab4d916342d9ba4467e6b9 wrongly attempted to read past the end of the currently-installed dtv to determine if a dso provides new, not-already-installed tls. this logic was probably leftover from an earlier draft of the code that wrongly installed the new dtv before populating it. it would work if we instead queried the new, not-yet-installed dtv, but instead, replace the incorrect check with a simple range check against old_cnt. this also catches modules that have no tls at all with a single condition.
