mds: fix error hanlding in MDCache::handle_discover_reply()
The error hanlding code in MDCache::handle_discover_reply() has two
main issues. MDCache::handle_discover_reply() does not wake waiters
if dir_auth_hint in reply message is equal to itself's nodeid. This
can happen if discover race with subtree importing. Another issue is
that it checks the existence of cached directory fragment to decide
if it should take waiter from inode or from directory fragment. The
check is unreliable because subtree importing can add directory
fragments to the cache.

mds: set want_base_dir to false for MDCache::discover_ino()
When frozen inode is encountered, MDCache::handle_discover() sends
reply immediately if the reply message is not empty. When handling
"discover ino" requests, the reply message always contains the base
directory fragment. But requestor already has the base directory
fragment, the only effect of the reply message is wake the requestor
and make it send same "discover ino" request again. So the requestor
keeps sending "discover ino" requests but can't make any progress.
The fix is set want_base_dir to false for MDCache::discover_ino().
After set want_base_dir to false, also need update the code that
handles "discover ino" error.
This patch also remove unused error handling code for flag_error_dn

osd: fix pg stat msgs vs timeout
We can get a pattern like so:
- new mon session
- after say 120 seconds, we decide to send a stats msg
- outstanding_pg_stats is finally true, we immediately time out (30 second
grace), and reconnect to a new mon
-> repeat
The problem is that we don't reset the last_sent timestamp when we send.
Or that we do this check after sending instead of before. Fix both.
This should resolve the issue #3661 where osds that don't have pgs
updating are not stats messags to the mon to check in, and are eventually
getting marked down as a result.
