Remove residual NULL-pstate handling in addRangeTableEntry.

Browse Source 
Passing a NULL pstate wouldn't actually work, because isLockedRefname()
isn't prepared to cope with it; and there hasn't been any in-core code
that tries in over a decade.  So just remove the residual NULL handling.

Spotted by Coverity; analysis and patch by Michael Paquier.
