[PATCH 3/8] docs: kdoc: don't add broken comments inside prototypes

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Parsing a file like drivers/scsi/isci/host.h, which contains
broken kernel-doc markups makes it create a prototype that contains
unmatched end comments.

That causes, for instance, struct sci_power_control to be shown this
this prototype:

    struct sci_power_control {
        * it is not. */ bool timer_started;
        */ struct sci_timer timer;
        * requesters field. */ u8 phys_waiting;
        */ u8 phys_granted_power;
        * mapped into requesters via struct sci_phy.phy_index */ struct isci_phy *requesters[SCI_MAX_PHYS];
    };

as comments won't start with "/*" anymore.

Fix the logic to detect such cases, and keep adding the comments
inside it.
