2023-12-06md: fix stopping sync threadYu Kuai
Currently sync thread is stopped from multiple contex: - idle_sync_thread - frozen_sync_thread - __md_stop_writes - md_set_readonly - do_md_stop And there are some problems: 1) sync_work is flushed while reconfig_mutex is grabbed, this can deadlock because the work function will grab reconfig_mutex as well. 2) md_reap_sync_thread() can't be called directly while md_do_sync() is not finished yet, for example, commit 130443d60b1b ("md: refactor idle/frozen_sync_thread() to fix deadlock"). 3) If MD_RECOVERY_RUNNING is not set, there is no need to stop sync_thread at all because sync_thread must not be registered. Factor out a helper stop_sync_thread(), so that above contex will behave the same. Fix 1) by flushing sync_work after reconfig_mutex is released, before waiting for sync_thread to be done; Fix 2) bt letting daemon thread to unregister sync_thread; Fix 3) by always checking MD_RECOVERY_RUNNING first.

2023-12-06md: don't leave 'MD_RECOVERY_FROZEN' in error path of md_set_readonly()Yu Kuai
If md_set_readonly() failed, the array could still be read-write, however 'MD_RECOVERY_FROZEN' could still be set, which leave the array in an abnormal state that sync or recovery can't continue anymore. Hence make sure the flag is cleared after md_set_readonly() returns.

2023-12-06md: fix missing flush of sync_workYu Kuai
Commit ac619781967b ("md: use separate work_struct for md_start_sync()") use a new sync_work to replace del_work, however, stop_sync_thread() and __md_stop_writes() was trying to wait for sync_thread to be done, hence they should switch to use sync_work as well. Noted that md_start_sync() from sync_work will grab 'reconfig_mutex', hence other contex can't held the same lock to flush work, and this will be fixed in later patches.
