[PATCH] RISC-V: hwprobe: Remove __init on probe_vendor_features()

[Evan Green]

probe_vendor_features() is now called from smp_callin(), which is not
__init code and runs during cpu hotplug events. Remove the
__init_or_module decoration from it and the functions it calls to avoid
walking into outer space.

Fixes: 62a31d6e38bd ("RISC-V: hwprobe: Support probing of misaligned access performance")
