btrfs: protect space cache inode alloc with GFP_NOFS
commit 84de76a2fb217dc1b6bc2965cc397d1648aa1404 upstream.
If we're allocating a new space cache inode it's likely going to be
under a transaction handle, so we need to use memalloc_nofs_save() in
order to avoid deadlocks, and more importantly lockdep messages that
make xfstests fail.
