[PATCH 07/18] net: liquidio: fix mixed module-builtin object

[Alexander Lobakin <alobakin@pm.me>]

From: Masahiro Yamada <masahiroy@kernel.org>

With CONFIG_LIQUIDIO=m and CONFIG_LIQUIDIO_VF=y (or vice versa),
$(common-objs) are linked to a module and also to vmlinux even though
the expected CFLAGS are different between builtins and modules.

This is the same situation as fixed by commit 637a642f5ca5 ("zstd:
Fixing mixed module-builtin objects").

Introduce the new module, liquidio-core, to provide the common functions
to liquidio and liquidio-vf.

[ alobakin: added export of lio_get_state_string() ]
