Revert "scsi: core: Use 32-bit hostnum in scsi_host_lookup()"

Browse Source 
This reverts commit f06c7d823a which is
commit 62ec2092095b678ff89ce4ba51c2938cd1e8e630 upstream.

It breaks the Android ABI and is not needed for Android systems at this
point in time.  If needed in the future, it can come back in an abi-safe
way.
