Btrfs: mark mapping with error flag to report errors to userspace

According to commit e1cfa6c463b6b404f5a33fee7e2d9d3d0dab45a1
(fs: fix fsync() error reporting),
it's not stable to just check error pages because pages can be
truncated or invalidated, we should also mark mapping with error
flag so that a later fsync can catch the error.
