isci: preallocate remote devices
Until we synchronize against device removal this limits the damage of
use after free bugs to the driver's own objects. Unless we implement
reference counting we need to ensure at least a subset of a remote
device is valid at all times. We follow the lead of other libsas
drivers that also preallocate devices.
This also enforces maximum remote device accounting at the lldd layer,
but the core may still run out of RNC's before we hit this limit.
