btrfs: btrfs_root_readonly() broken on big-endian
commit 6ed3cf2cdfce4c9f1d73171bd3f27d9cb77b734e upstream. ->root_flags is __le64 and all accesses to it go through the helpers that do proper conversions. Except for btrfs_root_readonly(), which checks bit 0 as in host-endian... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
