powerpc/process: Replace an #ifdef CONFIG_PPC_BOOK3S_64 by IS_ENABLED() 

This #ifdef CONFIG_PPC_BOOK3S_64 calls preload_new_slb_context()
when radix is not enabled.

radix_enabled() is always defined, and the prototype for
preload_new_slb_context() is always present, so the #ifdef
is unneeded.

Replace it by IS_ENABLED().
