[PATCH v3] dm vdo: use get_random_u32() where appropriate

[PATCH v3] dm vdo: use get_random_u32() where appropriate

[David Carlier]

Use the typed random integer helpers instead of
get_random_bytes() when filling a single integer variable.
The helpers return the value directly, require no pointer
or size argument, and better express intent.
