[PATCH 2/5] Documentation: riscv: vector: Wrap control_argument struct definition in code block

[Bagas Sanjaya]

kernel test robot reports htmldocs warning:

Documentation/riscv/vector.rst:45: WARNING: Definition list ends without a blank line; unexpected unindent.

The warning is due to definition of control_argument struct, written
unformatted. Wrap it in code block with C syntax highlighting to fix the
warning.

Fixes: 412c68cfeeb178 ("riscv: Add documentation for Vector")
