tree/: Drop default_spi_probe_opcode for NULL case

A NULL func pointer is necessary and sufficient for the
condition `NULL func pointer => true' as to not need this
boilerplate as it implies default behaviour of a supported
opcode within the `check_block_eraser()` match supported loop.

Ran;
```
$  find . -name '*.[c,h]' -exec sed -i '/.probe_opcode	= default_spi_probe_opcode,/d' '{}' \;
```
