[RFC PATCH] net/iucv: Descend into net/iucv when AFIUCV is enabled

[Pengpeng Hou]

AFIUCV can be enabled by the QETH_L3/HiperSockets path even when IUCV
itself is not enabled.  However, the top-level net Makefile only descends
into net/iucv/ under CONFIG_IUCV.

That creates a Kconfig/Kbuild carrier mismatch: CONFIG_AFIUCV=m can be
selected, but af_iucv.o is never considered because the containing
directory is skipped.

This RFC uses an always-descend model for net/iucv/.  The subdirectory
Makefile already gates iucv.o and af_iucv.o on their own Kconfig symbols,
so entering the directory does not force either provider object on.

This is intentionally RFC because s390 maintainers should confirm whether
the QETH_L3-only AF_IUCV configuration is intended to build af_iucv.o
without the base IUCV object.
