btrfs: avoid re-searching tree when converting bits in an extent range
When converting bits for an extent range (btrfs_convert_extent_bit()), if the current extent state record starts after the target range, we always do a jump to the 'search_again' label, which will cause us to do a full tree search for the next state if the current state ends before the target range. Unless we need to reschedule, we can just grab the next state and process it, avoiding a full tree search, even if that next state is not contiguous, as we'll allocate and insert a new prealloc state if needed.
