Subject: [PATCH] mdopen: always try create_named_array()

mdopen() will use create_named_array() to ask the kernel to create the
given md array, but only if it is given a number or name.
If it is NOT given a name and is required to choose one itself using
find_free_devnm() it does NOT use create_named_array().

On kernels with CONFIG_BLOCK_LEGACY_AUTOLOAD not set, this can result in
failure to assemble an array.  This can particularly seen when the
"name" of the array begins with a host name different to the name of the
host running the command.

So add the missing call to create_named_array().
