RDMA/rnbd: Fix compilation error when CONFIG_MODULES is disabled

module_is_live function is only defined when CONFIG_MODULES is enabled.
Use try_module_get instead to check whether the module is being removed.

When module unload and manuall unmapping is happening in parallel, we can
try removing the symlink twice: rnbd_client_exit
vs. rnbd_clt_unmap_dev_store.

This is probably not the best way to deal with this race in general, but
for now this fixes the compilation issue when CONFIG_MODULES is disabled
and has no functional impact. Regression tests passed.
