qcacld-3.0: Avoid deinit of TSO Seg lists if not initialized during pdev attach

Fix to avoid deinit of tso seg list and tso num seg list
during pdev detach if the lists are not initialized during
pdev post attach.

Currently, if htt_attach() fails as part of ol_txrx_post_pdev_attach(),
then it immediately returns from the function and not initializes
tso seg lists and during pdev_detach(), host tries to de-initialize
tso seg list and end up in a crash.
