 Log Message:
 in cpu_dumpconf(), don't panic() if we can't bdevsw_lookup() the
 dumpdev.  this occurs when we try to set the dumpdev to a device
 with no driver loaded.  this fixes PR#34872.
 
 in sys_swapctl, if bdevsw_lookup() fails, set dumpdev = NODEV
 before calling cpu_dumpconf().  (this also fixes PR#34872.)
 
 XXX: cpu_dumpconf() should probably be changed to take a dumpdev
 XXX: and return an error in such cases, but that is a much more
 XXX: intrusive change.
 
 XXX2: this is only run-tested on sparc64 and compile tested on a
 XXX2: couple of platforms.
