Additional fix to readline_into_buffer() with CONFIG_CMDLINE_EDITING before relocating

Removed unneeded command line history initialization.  Also, the original
code would access the 'initted' variable before relocation to SDRAM
which resulted in erratic behavior since the bss is not initialized when
executing from flash.
