[SCSI] initio: fix module hangs on loading

I've verified (on my Initio 9100 with a DAT drive) that the
2.6.24-rc8-git6 initio module still hangs on loading.

These fixes (other than the printk) are needed to get the module to load
ok (and work correctly) with my adapter & tape drive.

a) printk cosmetic fix

b) cblk->sglen needs setting for later DMA I/O routines to use

c) host->bios_addr needs setting for debug output correctness

d) semaph & semaph_lock initialisation had got lost since 2.6.22

e) since 2.6.22 the bios data address was truncated to 16 bits (needs 20
when shifted left)
