Alex Elder db2388b6ee rbd: verify rbd image order value 
This adds a verification that an rbd image's object order is
within the upper and lower bounds supported by this implementation.

It must be at least 9 (SECTOR_SHIFT), because the Linux bio system
assumes that minimum granularity.

It also must be less than 32 (at the moment anyway) because there
exist spots in the code that store the size of a "segment" (object
backing an rbd image) in a signed int variable, which can be 32 bits
including the sign.  We should be able to relax this limit once
we've verified the code uses 64-bit types where needed.

Note that the CLI tool already limits the order to the range 12-25.
