ocfs2: drop a VLA in ocfs2_orphan_del()
Avoid a VLA by using a real constant expression instead of a variable.
The compiler should be able to optimize the original code and avoid
using an actual VLA. Anyway this change is useful because it will avoid
a false positive with -Wvla, it might also help the compiler generating
better code.
