Brian Behlendorf 0365064a97 Handle closing an unopened ZVOL 
Thank to commit a4430fce69 we're
now correctly returning EROFS when opening a zvol on a read-only
pool.  Unfortunately, it looks like this causes us to trigger
some unexpected behavior by __blkdev_get().

In the failure case it's possible __blkdev_get() will call
__blkdev_put() for a bdev which was never successfully opened.
This results in us trying to close the device again and hitting
the NULL dereference.
