[PATCH] xfs: clear PF_NOFREEZE for xfsaild kthread

[Jiri Kosina <jikos@xxxxxxxxxx>]

From: Jiri Kosina <jkosina@xxxxxxx>

Since xfsaild has been converted to kthread in 0030807c, 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).
