Subject: [PATCH]   Catch errors when mounting invalid cramfs partitions.

When barebox is attempting to mount a cramfs partition with a bad magic, the
device will report success, but becomes unresponsive when trying to do any
file operations. The problem is caused by a missed error in cramfs_probe().
