[PATCH] Fix romfs void pointer compile error

[Jody Bruchon <jody@xxxxxxxxxxxxxxx>]

commit 82afea9a87740a766e5f2683bf27b312aab95572
Author: Jody Bruchon <jody@xxxxxxxxxxxxxxx>
Date:   Sat Feb 11 01:17:00 2012 -0500

    In elks/fs/romfs/inode.c, the function romfs_copyfrom() accepts
    Void *dest, but an invalid lvalue error was generated by this:

      ((char *)dest) += maxsize;

    By asking for char *dest instead, the function compiles properly.
    Since romfs is "in development," I cannot test the code, but it
    at least compiles now.
