tc-i386.c s_insn and input_line_pointer

A comment in check_Scc_OszcOperations says:
      /* No need to save/restore input_line_pointer; that's done in the
	 caller already.  */
That isn't true always.  Fix a case where input_line_pointer is not
restored and ignore_rest_of_line() accesses a wild pointer.

	* gas/config/tc-i386.c (s_insn <bad>): Restore input_line_pointer.
