e008db08e7 rpc: Add state_mask to each RPC method to make sets of RPCs
Add state_mask to each RPC method and state to RPC server, respectively.
State mask of RPC method is set at registration. State of RPC server
is changed according to the state of the SPDK.

When any RPC method is recieved, if the bit of the RPC server is on in
the state mask of the RPC method, it is allowed. Otherwise, it is
rejected.

When any RPC is rejected by state_mask control, the new error code
is returned to describe the error clearly.

3a6ff82760 nbd: fix hidden danger caused by stop rpc
If occasionally there is unflushed data in kernel,
nbd disconnect ioctl will not return, until these
data are flushed. spdk_nbd_disk should process these
data in flushing.
But at present, spdk_nbd_disk is running on a some
reactor with rpc. It is a hidden danger of deadlock.
