fs: namespace: drop BUG_ON() in copy_mnt_ns()
The sole caller, create_new_namespaces(), always passes a valid mount
namespace pointer from the task's nsproxy. The other copy_*_ns()
helpers, e.g. copy_time_ns() and copy_pid_ns(), don't perform such a
check either. Drop the BUG_ON() for consistency with them.
