Btrfs: mark mapping with error flag to report errors to userspace
According to commit 865ffef3797da2cac85b3354b5b6050dc9660978 (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.
