Subject: [PATCH 081/359] Manage: when re-adding, do check avail size if ->sb
 cannot be found.
References: bsc#1081910

avail_size1 requires ->sb, so we must only call it if ->sb
was loaded.

If ->sb wasn't loaded, then we are only proceding on the basis that
the kernel might be able to work something out - we don't need to
do any tests on size.
