performance/quick-read: fix race-conditions in qr_unlink.

The list of fds on which open needs to be done as part of unlink,
was being modified at different places using different locks.
This resulted in a race-condition where open was marked as in-transit,
but fdctx was removed from the list of fds on which open was being
sent even before open was done. Because of this, open_in_transit would
be set forever (as an open was never actually sent, there would be no
open_cbk called and hence we could not reset the variable), blocking
all the future fd based fops on this fd.
