[PATCH] x86/vector: Add missing annotation for void lock_vector_lock() and unlock_vector_lock()

[Jules Irenge <jbi.octave@gmail.com>]

Sparse reports a warning at lock_vector_lock() and unlock_vector_lock()

The root cause is the missing annotations at lock_vector_lock() and unlock_vector_lock()

Add the missing __acquires(&vector_lock)
Add the missing __releases(&vector_lock)
