librbd: clarify license header

These were meant to say LGPL, but a typo was propagated and it
referred to the non-existent GPL2.1, and also to COPYING which
correctly indicated these files were LGPL2.1.

RadosClient: Avoid the DispatchQueue for OSD responses.

Prior to this change, reader thread puts the response on the DispatchQueue
and Dispatcher thread would call librados callbacks (C_aio_Ack, C_Safe_Cond).
The single DispatchQueue and Dispatcher thread (per client) would become
a bottleneck with multiple OSDs in the cluster.
Similar to fast-dispatch changes on the OSD, DispatchQueue/thread are removed
and librados internal callbacks will be called from reader thread context.
