improve bsg device allocation

This patch addresses on two issues on bsg device allocation.

- the current maxium number of bsg devices is 256. It's too small if
we allocate bsg devices to all SCSI devices, transport entities, etc.
This increses the maxium number to 32768 (taken from the sg driver).

- SCSI devices are dynamically added and removed. Currently, bsg can't
handle it well since bsd_device->minor is simply increased.

This is dependent on the patchset that I posted yesterday:
