Remove an extra set of redundant parenthesis.

Note that changing sysctl types is technically not a style change since userland code which reads the value using an int will be broken. We've had regressions in the past when a similar change was merged to a stable branch. I think it's fine in this case: we don't currently aim to preserve binary compatibility for RISC-V and I doubt that there is any C code that toggles this sysctl.

Since you're changing the type, could you also move the sysctl under the debug OID? Maybe debug.kld_reloc or so.

I'd also get rid of the blank lines around this assignment.

405–407

The indentation is still wrong here.
