mainline inclusion
from mainline-v5.10-rc2
commit 9c2bb257
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HJSI
CVE: CVE-2024-26846

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9c2bb2577d81b1a09f7e342e947986e55cad18e3



--------------------------------

err_work was created to handle errors (mainly I/O timeouts) while in
CONNECTING state. The flag for err_work_active is also unneeded.

Remove err_work_active and err_work.  The actions to abort I/Os are moved
inline to nvme_error_recovery().
