eficonfig: carve out efi_get_next_variable_name_int calls
To retrieve the EFI variable name by efi_get_next_variable_name_int(),
the sequence of alloc -> efi_get_next_variable_name_int ->
realloc -> efi_get_next_variable_name_int is required.
In current code, this sequence repeatedly appears in
the several functions. It should be curved out a common function.
This commit also fixes the missing free() of var_name16
in eficonfig_delete_invalid_boot_option().
