[KUDU-3452] Make validate tablet creating task not affected

Currently, creating a table with RF=n when the number of
healthy tservers is less than n will get stuck. Because
catalog manager creates tablets for it will fail and retry
continuously. At the same time, creating a table with RF=m
also will get stuck even if there are more than m healthy
tservers. Because catalog manager will return when finds a
tablet-creating task failed and will not try to select replicas
for other PREPARING tablets. For example, creating a three
replicas table times out when one of three tablet servers becomes
unavailable. After that, creating a two-replicas table also
will timeout even if there are enough tablet servers to place
its replicas. The validate two-replicas table-creating task will
be affected by invalidate three-replicas table-creating task.

This patch fixes this problem. If a task of creating tablet fail,
it will not return immediately, but let other tasks of creating
other tablets keep on running.
