bcachefs: Disable errors=panic for BCH_IOCTL_FSCK_OFFLINE
BCH_IOCTL_FSCK_OFFLINE allows the userspace fsck tool to use the kernel implementation of fsck - primarily when the kernel version is a better version match. It should look and act exactly like the normal userspace fsck that the user expected to be invoking, so errors should never result in a kernel panic. We may want to consider further restricting errors=panic - it's only intended for debugging in controlled test environments, it should have no purpose it normal usage.
