[PATCH 5.13 526/800] net: mana: Fix a memory leak in an error handling path in mana_create_txq()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit b90788459cd6d140171b046f0b37fad341ade0a3 ]

If this test fails we must free some resources as in all the other error
handling paths of this function.

Fixes: ca9c54d2d6a5 ("net: mana: Add a driver for Microsoft Azure Network Adapter (MANA)")
