nilfs2: fix possible recovery failure due to block creation without writer

Some function calls in nilfs_prepare_segment_for_recovery() may fail
because they can create blocks on meta data files without configuring
a writable FS-instance.  Concretely, nilfs_mdt_create_block() routine
of meta data files will fail in that case.

This fixes the problem by temporarily attaching a writable FS-instace
during the function is called.
