nl80211: MLD: Fix is_shared_drv ops logic when num links is one

Whenever there is only one BSS left and if the number of links is one,
is_shared_drv() returns false assuming no one else is sharing the driver
interface. However, when the number of links is one, this does not
guarantee that the caller's link ID is the only active link ID. If this
is not the case and false is returned, the caller calls hapd_deinit()
which will free the driver interface. However, when the actual active
link_id reaches deinit path, this leads to dereferencing a NULL pointer
ultimately leading to segmentation fault.

To prevent this, pass the link ID into the is_drv_shared() ops and match
it with only with active link IDs. Only return false if they are same.
