Christoph Hellwig 0cc6eee130 xfs: avoid memory allocation under m_peraglock in growfs code 
Allocate the memory for the larger m_perag array before taking the
per-AG lock as the per-AG lock can be taken under the i_lock which
can be taken from reclaim context.

Reported by the new reclaim context tracing in lockdep.
