riscv: Fix fast_unaligned_access_speed_key not getting initialized
de97eb2 
The static key fast_unaligned_access_speed_key is supposed to be
initialized after check_unaligned_access_all_cpus() has been completed.

However, check_unaligned_access_all_cpus() has been moved to late_initcall
while setting fast_unaligned_access_speed_key still happens at
arch_initcall_sync, thus the static key does not get properly initialized.

fast_unaligned_access_speed_key can still be initialized in CPU hotplug
events, but that cannot be relied on.

Move fast_unaligned_access_speed_key's initialization into
check_unaligned_access_all_cpus() to fix this issue. This also prevent
someone from moving one initcall while forgetting the other in the future.

Fixes: 6455c6c ("riscv: Clean up & optimize unaligned scalar access probe")
