RISC-V: Fix indentation of "length" attribute for branches and jumps
The "length" attribute calculation expressions for branches and jumps
are incorrectly and misleadingly indented, and they overrun the 80
column limit as well, all of this causing troubles in following them.
Correct all these issues.

jump length calculation expressions.
