binnfmt:Fix return before close ELF fd

elf_init open a elf file , if both enabled
   CONFIG_NSH_BUIlTAPPS and CONFIG_NSH_FILE_APPS ,
   elf_init will read elf file in /bin directory, but
   that length is zero , elf_read failed return and NOT
   close elf fd, so this line MUST be return to errout_with_init
