[PATCH kmod 13/13] libkmod: always fallback to do_init_module()

[Emil Velikov via B4 Relay <devnull+emil.l.velikov.gmail.com@kernel.org>]

From: Emil Velikov <emil.l.velikov@gmail.com>

Since the direct loading was introduced a few bugs became obvious that
the compression args used were off - both in-kernel and dkms.

While both of those are fixed already, not all of those have reached all
users. For example: for dkms I'm aiming to do a release just as kmod has
theirs (to align /lib/modules <> /usr/lib/modules support).

Although I am wondering if we can indiscriminatingly callback to the old
do_init_module() in all the cases. This means that we'll catch any
in-kernel decompression issues - invalid args, ENOMEM, other....
Although for others (wrong magic, perm, etc) we will end up doing the
exact kernel work twice.

Overall the trade-off seems worth it, so flip this.
