Norman Feske 67a3c2ea4b sculpt: handle failures of usb_block_drv
This patch handles the situation where the usb_block_drv exits for any
reason, in particular when the driver fails to initialize the device. In
such cases, the usb_block_drv used to stay stale in the system,
effectively preventing the device from being passed to a VM. With the
patch, the USB storage device gets flagged as failed, the usb_block_drv
is removed from the runtime, and the condition is reflected at the user
interface.

This situation occurred on the attempt to access an iomega zip drive
with a version of the usb_block_drv without support for the START-STOP
command, but it may potentially also occur in other circumstances.

Fixes #3468

This directory is a source-code repository containing Genode-specific
services and applications. In contrast to the components that come with
the 'os' repository, programs contained in 'gems' are able to leverage
the functionalities provided by higher-level repositories such as 'libports'.
To use the 'gems' repository, make sure to also add those repositories to your
build configuraion.
