sunrpc: convert unnecessary GFP_ATOMIC to GFP_NOFS
It's OK to sleep here, we just don't want to recurse into the filesystem
as a writeout could be waiting on this.
Future work: the documentation for GFP_NOFS says "Please try to avoid
using this flag directly and instead use memalloc_nofs_{save,restore} to
mark the whole scope which cannot/shouldn't recurse into the FS layer
with a short explanation why. All allocation requests will inherit
GFP_NOFS implicitly."
But I'm not sure where to do this. Should the workqueue be arranging
that for us in the case of workqueues created with WQ_MEM_RECLAIM?
