init: remove unused names parameter in split_fs_names()

The split_fs_names() function takes a names parameter, but the function
actually uses the root_fs_names global variable instead. This names
parameter is not used in the function, so it can be safely removed.

This change does not affect the functionality of split_fs_names() or any
other part of the kernel.
