Brian Behlendorf abd39a8289 Fix zio_execute() deadlock 
To avoid deadlocking the system it is crucial that all memory
allocations performed in the zio_execute() call path are marked
KM_PUSHPAGE (GFP_NOFS).  This ensures that while a z_wr_iss
thread is processing the syncing transaction group it does
not re-enter the filesystem code and deadlock on itself.
