nilfs2: fix potential hang in nilfs_error on errors=remount-ro
nilfs_error() calls nilfs_detach_segment_constructor() if
errors=remount-ro option is specified, and this may lead to a hang due
to recursive locking of, for instance, nilfs->ns_segctor_sem and
others.
In this case, detaching segment constructor is not necessary because
read-only flag is set to the filesystem and further writes are
blocked.
This fixes the potential hang issue by removing the
nilfs_detach_segment_constructor() call from nilfs_error.
