nilfs2: do not propagate ENOENT error from sufile during recovery
nilfs_sufile_free() returns the error code -ENOENT when the block where
the segment usage should be placed does not exist (hole block case), but
this error should not be propagated upwards to the mount system call.
In nilfs_prepare_segment_for_recovery(), one of the recovery steps during
mount, nilfs_sufile_free() is used and may return -ENOENT as is, so in
that case return -EINVAL instead.
