Fixes issue #1168.
Remove a call to abort() (introduced by commit
0e725b5d9b) made when SWIG_RubyUnlinkObjects()
is called on non T_DATA objects. It can happen when the destruction of T_DATA
objects is deferred: the Ruby GC first turn them to T_ZOMBIE, then calls their
free method (SWIG_RubyUnlinkObjects()).
