kernel-shared: uapi: fix BTRFS_IOC_SCAN_DEV defiintion
Without the change `BTRFS_IOC_SCAN_DEV` aliased with `BTRFS_IOC_FORGET_DEV`.
It's a regression introduced in fcd9142b6 "btrfs-progs: docs: formatting,
fixups, updates".
It manifests as a sudden device disappearance when device is scanned:
machine # [ 4.095032] Btrfs loaded, crc32c=crc32c-intel, zoned=no, fsverity=no
machine # ERROR: device scan failed on '/dev/vdb': No such file or directory
machine # ERROR: device scan failed on '/dev/vdc': No such file or directory
(finished: must succeed: mkfs.btrfs -d raid0 /dev/vdb /dev/vdc, in 10.31 seconds)
Issue: #704
