kernel: Fix spinlock_acquire() flaw
This commit fixes a spinlock_acquire() flaw and corrects a [quite an implausible] mistake, in which we do not even spin. It would have been fine how it was before in Vega's contemporary state; however, not a good idea to keep. Signed-off-by: sigsegv7 <ian@vegaa.systems>
