Subject: [PATCH] KVM: VMX: replace "fall through" with "return true" to indicate different case

From: Miaohe Lin <linmiaohe@...wei.com>

The second "/* fall through */" in rmode_exception() makes code harder to
read. Replace it with "return true" to indicate they are different cases
and also this improves the readability.
