Changpeng Liu 90520634bd bdev/nvme: configure the number of requests allocated for one NVMe I/O queue via RPC 
A single I/O may allocate more than one request, since splitting may be
necessary to conform to the device's maximum transfer size, PRP list
compatibility requirements, or driver-assisted striping.  Very big
I/O request sent from application may get error due to limited resources
in NVMe driver layer, so here we add an optional parameter to make the
parameter can be configured by users.

Fix issue #745.
