[PATCH 13/13] arc: do not use __print_symbol()

[Sergey Senozhatsky <sergey.senozhatsky.work@xxxxxxxxx>]

__print_symbol() uses extra stack space to sprintf() symbol
information and then to feed that buffer to printk()

  char buffer[KSYM_SYMBOL_LEN];

  sprint_symbol(buffer, address);
  printk(fmt, buffer);

Replace __print_symbol() with a direct printk("%pS") call.
