Commit 92cc6708f4 ("selftests: rds: config: disable modules") set
CONFIG_MODULES=n since run.sh required this kconfig. But disabling
modules also forces every =m option to =n rather than =y, which can
silently drop unrelated features.
This patch removes CONFIG_MODULES=n from the rds selftest config and
updates the check_*conf_enabled() routines to accept a config as
either built-in (=y) or modular (=m). A new probe_module() function
is added to load the backing module when a component is set to be
modular (=m). config.sh no longer forces CONFIG_MODULES=n, so a user
who follows the SKIP message to run config.sh does not silently end
up with modules disabled again.
rds.ko itself is auto-loaded on socket creation, and rds_rdma.ko is
auto-loaded when SO_RDS_TRANSPORT is set with RDS_TRANS_IB, but the
TCP transport (rds_tcp.ko) is not auto-loaded on the bind path, so
the backing modules are loaded explicitly here.
