xfs: switch to NOFS allocation under i_lock in xfs_da_state_alloc

Browse source 
xfs_da_state_alloc is always called with i_lock held, but i_lock is taken in
reclaim context so all allocations under it must avoid recursions into the
filesystem.

Reported by the new reclaim context tracing in lockdep.
