[PATCH, -tip] Remove redundant RCU_CPU_STALL_DETECTOR declaration

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

This patch removes the redundant RCU_CPU_STALL_DETECTOR Kconfig
parameter.  We got one from the classic RCU detector and the other
from the hierarchical RCU detector, this patch merges them.

This patch is suitable for inclusion.
