build: NlsCheck - unwrap else clause

Unwrapped a useless else clause, since the if clause does not terminate
properly (it returns from the function).

build: NlsCheck - proper inner class

Made the inner class QuotedString private static, as it is not used
outside this class and does not require access to the enclosing class'
members.

Also removed the redundant semicolon at the end of the declaration.

webadmin: Remove useless null check

Remove a useless null check from
VdcQueryReturnValue_CustomFieldSerializer's serialize and deserialize
methods.

nulls are checked explicitly in the begging of the respective functions,
so it cannot be null at their ends.
