8289763: Remove NULL check in CDSProtectionDomain::init_security_info()

[iklam]

Please review this trivial clean up. I removed the unnecessary NULL check, and replaced the CHECK_(pd) with CHECK_NH to make the code cleaner.

[calvinccheung]

Since the null check for ik has been removed, I'm wondering if it makes sense to add an assert that ik is non-null?
(I noticed the caller already has a null check before calling the function.)

[iklam]

There are many functions that require input parameters to be non-NULL without explicitly asserting them. I think in this case, the API is quite obvious that a NULL class shouldn't be passed, so I think an assert is not necessary.

[calvinccheung]

The cleanup of CHECK_ looks good. Thanks.

[coleenp]

Looks good and trivial to me.
