[Clang][CodeGen][UBSan] Remove redundant EmitCheckValue calls. NFCI (#135141)

Browse Source 
`EmitCheckValue` is called inside `EmitCheck`:

b122956390/clang/lib/CodeGen/CGExpr.cpp (L3739)
The outside calls are redundant because
`EmitCheckValue(EmitCheckValue(V))` always returns `EmitCheckValue(V)`.

Required by https://github.com/llvm/llvm-project/pull/135135.
