ext4: Initialize preallocation list_head's properly
(cherry picked from commit d794bf8e0936dce45104565cd48c571061f4c1e3)
When creating a new ext4_prealloc_space structure, we have to
initialize its list_head pointers before we add them to any prealloc
lists. Otherwise, with list debug enabled, we will get list
corruption warnings.
