net/af_iucv: clean up a try_then_request_module()
[ Upstream commit 4eb9eda6ba64114d98827e2870e024d5ab7cd35b ]
Use IS_ENABLED(CONFIG_IUCV) to determine whether the iucv_if symbol
is available, and let depmod deal with the module dependency.
This was introduced back with commit 6fcd61f7bf5d ("af_iucv: use
loadable iucv interface"). And to avoid sprinkling IS_ENABLED() over
all the code, we're keeping the indirection through pr_iucv->...().
