scsi: storvsc: Miscellaneous code cleanups
As general cleanup and in preparation for subsequent patches:
- Use min() instead of open coding.
- Use set_host_byte() instead of open coding access to scsi_status
field.
- Collapse nested "if" statements to reduce indentation.
- Fix other indentation.
- Remove extra blank lines.
No functional changes.
[mkp: dropped status_byte() which no longer exists]
