This patch removes the ls_remove_wait waitqueue handling. The current handling tries to wait before a lookup is send out for a identically resource name which is going to be removed. Hereby the remove message should be send out before the new lookup message. The reason is that after a lookup request and response will actually use the specific remote rsb. A followed remove message would delete the rsb on the remote side but it's still being used. To reach a similar behaviour we simple send the remove message out while the rsb lookup lock is held and the rsb is removed from the toss list. Other find_rsb() calls would never have the change to get a rsb back to live while a remove message will be send out (without holding the lock). This behaviour requires a non-sleepable context which should be provided now and might be the reason why it was not implemented so in the first place.
