bcachefs: preserve device path as device name
Various userspace scripts/tools may expect mount entries in /proc/mounts to reflect the device path names used to mount the associated filesystem. bcachefs seems to normalize the device path to the underlying device name based on the block device. This confuses tools like fstests when the test devices might be lvm or device-mapper based. The default behavior for show_vfsmnt() appers to be to use the string passed to alloc_vfsmnt(), so tweak bcachefs to copy the path at device superblock read time and to display it via ->show_devname().
