rgw/rgw_formats.cc: fix realloc memory leak

Fix handling of realloc. If realloc() fails it returns NULL, assigning
the return value of realloc() directly to the pointer without checking
for the result will lead to a memory leak in error case.

Use a temporary pointer to hold the result of realloc(). In error case
print error and exit, otherwise assign it to the pointer we want to realloc.

Fix also error checks for malloc to fail as soon as malloc fails and
don't try to run realloc again after failed malloc.

osdc/Objecter: fix tick_event handling in shutdown vs tick race

If we fail to cancel the tick_event, we rely on tick() itself to clear
tick_event.  I'm not quite sure how we got this wrong in the previous
commit, but this boils down to two cases:

1) shutdown() successfully cancels the event and clears tick_event.  tick()
   never runs.  tick_event == NULL when we finish.
2) shutdown() fails to cancel the event because it has already started.  In
   this case tick itself is blocking (or about to block) waiting on the
   rlock.  When it does run it will clear tick_event itself, then see
   initiazed == 0 and exit without rescheduling.
