cxgb4: fix missing unlock on ETHOFLD desc collect fail path
stable inclusion from stable-v5.10.147 commit 2c248c4681620e76d42ef16a14050e26bd07702d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0W8 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=2c248c4681620e76d42ef16a14050e26bd07702d -------------------------------- [ Upstream commit c635ebe8 ] The label passed to the QDESC_GET for the ETHOFLD TXQ, RXQ, and FLQ, is the 'out' one, which skips the 'out_unlock' label, and thus doesn't unlock the 'uld_mutex' before returning. Additionally, since commit 5148e595 ("cxgb4: add EOTID tracking and software context dump"), the access to these ETHOFLD hardware queues should be protected by the 'mqprio_mutex' instead.
