Nicholas Piggin 89bbe4c798 powerpc/64: indirect function call use bctrl rather than blrl in ret_from_kernel_thread 
blrl is not recommended to use as an indirect function call, as it may
corrupt the link stack predictor.

This is not a performance critical path but this should be fixed for
consistency.
