btrfs: fail mount when sb flag is not in BTRFS_SUPER_FLAG_SUPP

btrfs: fail mount when sb flag is not in BTRFS_SUPER_FLAG_SUPP

[ Upstream commit 6f794e3c5c8f8fdd3b5bb20d9ded894e685b5bbe ]

It appears from the original commit [1] that there isn't any design
specific reason not to fail the mount instead of just warning. This
patch will change it to fail.
