[PATCH] Fixing memory leak of SePublicDefaultSd, SePublicDefaultUnrestrictedSd, SePublicOpenSd, SePublicOpenUnrestrictedSd, SeSystemDefaultSd in SepInitSDs (72645)

Hello,

I noticed that in SepInitSDs(...) we do not properly release the following variables under memory starvation scenarios:

• SePublicDefaultSd
• SePublicDefaultUnrestrictedSd
• SePublicOpenSd
• SePublicOpenUnrestrictedSd
• SeSystemDefaultSd

The probability of this is very low and the system has to be in low memory condition, but it still a bug and I decided to submit a patch for this.

This issue is related to CORE-11967 because the original problem happens under the same conditions: system is booting and a return of FALSE anyway will halt the OS.
