[PATCH] SELinux leak fixes

From: Stephen Smalley <sds@epoch.ncsc.mil>

I believe that the patch below fixes the legitimate leaks in the SELinux
code.  In some cases, it rearranges the code (moving the allocation later
to reduce the need for further cleanup or linking the object into a
containing structure earlier so that the policydb_destroy will handle it
upon any subsequent errors).
