1. mon/OSDMonitor: Ensure kvmon() is writeable before handling "osd new"… …

   … cmd
   
   Before proceeding to handle "osd new" mon command as part of
   OSDMonitor::prepare_command_impl(), a check is made to verify if the
   authmon is writeable. Later on, prepare_command_osd_new() invokes
   KVMonitor::do_osd_new() to create pending dmcrypt keys and calls
   propose_pending(). The propose could fail (with an assertion failure)
   if there was a prior mon command that resulted in the kvmon invoking
   propose_pending().
   
   In order to avoid such a situation, introduce a check to verify that
   kvmon is also writeable in OSDMonitor::prepare_command_impl(). If it
   is not writeable, the op is pushed into the wait_for_active context
   queue to be retried later.
