The 'mode' must be known from the beginning and changing it later on
would not be supported/meaningful. So, enforce this by setting the
property at construct time only.

There seems to be the possibility of a race while reading tun
properties from sysctl. In this case, when being unable to
read the properties at construction of NMDeviceTun, we retry
shortly after.
- let tun_get_properties() not log any errors and it
does not stop on the first error but tries to read all
the values. Also, it initializes all fields of the output
structure with a default value (NULL).
- hard code kernel flag #ifndef in header files. Even if the
flag IFF_MULTI_QUEUE is not defined at compile time of NM,
it could still be supported by the kernel (eg. when booting
a newer kernel then the installed kernel headers). Simply
hard code the value, this value is not ever going to change
anyway.

Rather than passing UDI, ifname, and driver name to the device
constructors as separate arguments, just pass the NMPlatformLink
instead and let it parse them out.
Virtual types still take UDI and ifname separately, since we create
fake NMDevices for them for autoactivating connections. That's weird
in other ways too though, so perhaps this should be revisted.
