aoe: support more AoE addresses with dynamic block device minor numbers
The ATA over Ethernet protocol uses a major (shelf) and minor (slot) address to identify a particular storage target. These changes remove an artificial limitation the aoe driver imposes on the use of AoE addresses. For example, without these changes, the slot address has a maximum of 15, but users commonly use slot numbers much greater than that. The AoE shelf and slot address space is often used sparsely. Instead of using a static mapping between AoE addresses and the block device minor number, the block device minor numbers are now allocated on demand.
