cpu/SMT: State SMT is disabled even with nosmt and without "=force"

Browse source 
[ Upstream commit d0e7d14455d41163126afecd0fcce935463cc512 ]

When booting with "nosmt=force" a message is issued into dmesg to
confirm that SMT has been force-disabled but such a message is not
issued when only "nosmt" is on the kernel command line.

Fix that.
