[S390] vmcp cleanup
A number of small changes to vmcp:
- Change preferred email address.
- Use PRINT_xxx machros from debug.h like most s390 drivers, define
"vmcp:" as PRINTK_HEADER and wrap error message at column 80.
- Add error number to error message.
- Update copyright, as I touched this file.
- Small whitespace diff.
- Use mutex instead of semaphore (Thanks Heiko for the patch)
- Don't register debug feature on failure.
- Check debug feature registration on init to avoid a potential oops
on unload if the debug feature could not be registered--> 2 more
messages.
