Update outdated assertion from zio_write_compress 

As part of some internal gang block testing within Delphix
we hit the assertion removed by this patch. The assertion
was triggered by a ZIO that had two copies and was a gang
block making the following expression equal to 3:
```
MIN(zp->zp_copies + BP_IS_GANG(bp), spa_max_replication(spa))
```
and failing when we expected the above to be equal to
`BP_GET_NDVAS(bp)`.

The assertion is no longer valid since the following commit:
```
commit 14872aaa4f
Author: Matthew Ahrens <matthew.ahrens@delphix.com>
Date:   Mon Feb 6 09:37:06 2023 -0800

  EIO caused by encryption + recursive gang
```

The above commit changed gang block headers so they can't
have more than 2 copies but the assertion in question from
this PR was never updated.
