[PATCH] rcu/rcutorture: Improve error handling in rcu_torture_fwd_prog_init()

[Kaushlendra Kumar]

Restructure error handling in rcu_torture_fwd_prog_init() to provide
cleaner allocation failure paths. The current code checks both
allocations
in a single condition, making error handling less efficient and clear.

The improved approach:
- Check rfp allocation immediately and return early on failure
- Separately handle fwd_prog_tasks allocation failure with proper
  cleanup
- Remove redundant kfree(fwd_prog_tasks) since it would be NULL on
  failure
