Module Name:    src
Committed By:   pgoyette

Modified Files:
        src/sys/dev [prg-localcount2]: cgd.c

Log Message:
Fix checking of failure-to-spawn a unit (check the returned address for
NULL, vs the pointer to that address).

Ensure that that device_release() is called in all exit paths from cgd_close().

Update handling of CGDIOCCLR ioctl the same as CGDIOCSET.  In particular,
don't return without calling device_release(), as any subsequent attempt to
detach the device will hang forever waiting for its localcount to drain.
