loop: loop_thread needs to set the PF_LESS_THROTTLE flag

The underlying file system may call balance_dirty_pages. We don't want
it to throttle there since we may be in the process of writing dirty
pages. This patch addresses the problem in the same manner as a local
nfs mount, as nfsd does the same.
