preempt/dynamic: Fix setup_preempt_mode() return value
[ Upstream commit 9ed20bafc85806ca6c97c9128cec46c3ef80ae86 ]
__setup() callbacks expect 1 for success and 0 for failure. Correct the
usage here to reflect that.
Fixes: 826bfeb37bb4 ("preempt/dynamic: Support dynamic preempt with preempt= boot option")
