locks: fix error in locks_move_blocks()
After moving all requests from
fl->fl_blocked_requests
to
new->fl_blocked_requests
it is nonsensical to do anything to all the remaining elements, there
aren't any. This should do something to all the requests that have been
moved. For simplicity, it does it to all requests in the target list.
Setting "f->fl_blocker = new" to all members of new->fl_blocked_requests
is "obviously correct" as it preserves the invariant of the linkage
among requests.
