dsp: bios_table: Null check for pldm_bios_table_iter_is_end()

GCC's -fanalyzer identified the following:

```
In file included from ../tests/dsp/bios_table_iter.c:15:
../src/dsp/bios_table.c: In function ‘pldm_bios_table_iter_is_end’:
../src/dsp/bios_table.c:991:17: error: dereference of NULL ‘iter’ [CWE-476] [-Werror=analyzer-null-dereference]
  991 |         if (iter->table_len - iter->current_pos <= pad_and_check_max) {
      |             ~~~~^~~~~~~~~~~
```

As a safety measure, return true to indicate the end of the iterator if
the iterator is null.
