f2fs: quota: fix stale lock holder on remount failure
F2FS remount can fail while duplicating a journalled quota file name.
f2fs_remount()
- sbi->umount_lock_holder = current
- kstrdup(F2FS_OPTION(sbi).s_qf_names[i])
: fails
- free previously duplicated names
- return -ENOMEM
The direct return leaves umount_lock_holder pointing at the failed
remount context. A later checkpoint may then wrongly treat another
context as the s_umount lock holder.
Add a restore_holder cleanup path and use it before returning -ENOMEM.
