RDMA/cma: Fix unknown symbol when CONFIG_IPV6 is not enabled
If IPV6 has not been enabled in the underlying kernel, we must avoid
calling IPV6 procedures in rdma_cm.ko.
This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements
surrounding any code which calls external IPV6 procedures.
In the instance fixed here, procedure cma_bind_addr() called
ipv6_addr_type() -- which resulted in calling external procedure
__ipv6_addr_type().
