srcu: Remove superfluous sdp->srcu_lock_count zero filling

Browse source

Because alloc_percpu() zeroes out the allocated memory, there is no need
to zero-fill newly allocated per-CPU memory.  This commit therefore removes
the loop zeroing the ->srcu_lock_count and ->srcu_unlock_count arrays
from init_srcu_struct_nodes().  This is the only use of that function's
is_static parameter, which this commit also removes.
