Btrfs: make profile_is_valid() check more strict
"0" is a valid value for an on-disk chunk profile, but it is not a valid extended profile. (We have a separate bit for single chunks in extended case) Also rename it to alloc_profile_is_valid() for clarity. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
