cluster/ec: Don't trigger data/metadata heal on Lookups
Problem-1
If Lookup which doesn't take any locks observes version mismatch it can't be
trusted. If we launch a heal based on this information it will lead to
self-heals which will affect I/O performance in the cases where Lookup is
wrong. Considering self-heal-daemon and operations on the inode from client
which take locks can still trigger heal we can choose to not attempt a heal on
Lookup.
Problem-2:
Fixed spurious failure of
tests/bitrot/bug-1373520.t
For the issues above, what was happening was that ec_heal_inspect()
is preventing 'name' heal to happen
Problem-3:
tests/basic/ec/ec-background-heals.t
To be honest I don't know what the problem was, while fixing
the 2 problems above, I made some changes to ec_heal_inspect() and
ec_need_heal() after which when I tried to recreate the spurious
failure it just didn't happen even after a long time.
