xfs: clear PF_NOFREEZE for xfsaild kthread

Since xfsaild has been converted to kthread in 0030807, it calls try_to_freeze() during every AIL push iteration. It however doesn't set itself as freezable, and therefore this try_to_freeze() will never do anything. Before (hopefully eventually) kthread freezing gets converted to fileystem freezing, we'd rather mark xfsaild freezable (as it can generate I/O during suspend).
