mtd: Fixed breaking list in __mtd_del_partition.

Browse Source 
commit 2966daf7d253d9904b337b040dd7a43472858b8a upstream.

Not the child partition should be removed from the partition list
but the partition itself. Otherwise the partition list gets broken
and any subsequent remove operations leads to a kernel panic.
