The easiest way is to reinstate max_loop and create "max_loop" device
up front at module load time.  However, that will lose all the "fancy
on-demand device instantiation feature".

So I propose we do the following:

1. have the module honor "max_loop" parameter and create that many
device upfront on module load (max_loop will also be a hard max) iff
user specify the parameter.
2. if max_loop is not specified, default create 8 loop device.  User
can extent more loop device by create device node themselves and have
kernel automatically instantiate loop device on-demand.

Is this acceptable?  Patch in a bit.
