Bug description:
  OS version: Ubuntu 24.04
  package version: 18-1build2

  My PCs has boot entries 0010, 0020 and 0021.

  $ sudo efibootmgr
  BootCurrent: 0010
  Timeout: 1 seconds
  BootOrder: 0020,0010
  Boot0010* NORMAL	HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)/<<snip>>
  Boot0020* UPDATE	HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)/<<snip>>
  Boot0021* UEFI: TOSHIBA, Partition 1	PciRoot(0x0)/Pci(0x14,0x0)/USB(16,0)/HD(1,GPT,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0x800,0x80000)0000424f

  I tried to active/inactive 10 or 20 entry. But these are not found.

  $ sudo efibootmgr -A -b 0010
  efibootmgr: Boot entry 10 not found
  Could not set active state for Boot0010: No such file or directory
  $ sudo efibootmgr -A -b 0020
  efibootmgr: Boot entry 20 not found
  Could not set active state for Boot0020: No such file or directory
  $ sudo efibootmgr -a -b 0010
  efibootmgr: Boot entry 10 not found
  Could not set active state for Boot0010: No such file or directory
  $ sudo efibootmgr -a -b 0020
  efibootmgr: Boot entry 20 not found
  Could not set active state for Boot0020: No such file or directory

  I investigated the cause and found a problem with the get_entry()
  function in src/efibootmgr.c.

  static var_entry_t *
  get_entry(list_t *entries, uint16_t num)
  {
   list_t *pos;
   var_entry_t *entry = NULL;

   list_for_each(pos, entries) {
    entry = list_entry(pos, var_entry_t, list);
    if (entry->num != num) {
     entry = NULL;
     continue;
    }
   }

   return entry;
  }

  This code does not break the loop when an entry is found.
  Therefore, NULL is returned unless the matching entry is the last one.
