spl: Remove overwrite of relocated malloc limit

spl_init on some boards is called after stack and heap relocation, on
some platforms spl_relocate_stack_gd is called to handle setting the
limit to its value CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN when simple
SPL malloc is enabled during relocation. spl_init should then not
re-assign the old pre-relocation limit when this is defined.
