[PATCH v6 20/21] net/txgbe: fix to enable Tx desc check

[Zaiyu Wang <zaiyuwang@trustnetic.com>]

Now lib security is enabled by default, and cannot be disabled if the
driver is intended to be used. So Tdm_desc_chk is always unable to enable.
Remove this restriction, and just enable the corresponding queue check.

Fixes: 0eabdfcd4af4 ("net/txgbe: enable Tx descriptor error interrupt")
