When the send protocol versioning was added in 5.16 e77fbf990316
("btrfs: send: prepare for v2 protocol"), the 32/64bit compat code was
not updated (added by 2351f431f727 ("btrfs: fix send ioctl on 32bit with
64bit kernel")), missing the version struct member. The compat code is
probably rarely used, nobody reported any bugs.

Fixes: 2351f431f727 ("btrfs: fix send ioctl on 32bit with 64bit kernel")
