qemu-img: avoid calling exit(1) to release resources properly

Browse Source

This patch removes exit(1) from error(), and properly releases
resources such as a block driver and an allocated memory.

For testing the Sheepdog block driver with qemu-iotests, it is
necessary to call bdrv_delete() before the program exits.  Because the
driver releases the lock of VM images in the close handler.
