btrfs: switch GFP_ATOMIC to GFP_NOFS when fixing up low keys
When fixing up the first key of each node above the current level, at
fixup_low_keys(), we are doing a GFP_ATOMIC allocation for inserting an
operation record for the tree mod log. However we can do just fine with
GFP_NOFS nowadays. The need for GFP_ATOMIC was for the old days when we
had custom locks with spinning behaviour for extent buffers and we were
in spinning mode while at fixup_low_keys(). Now we use rw semaphores for
extent buffer locks, so we can safely use GFP_NOFS.
