srcu: Drop needless initialization of sdp in srcu_gp_start() 



Commit 9c7ef4c30f12 ("srcu: Make Tree SRCU able to operate without
snp_node array") initializes the local variable sdp differently depending
on the srcu's state in srcu_gp_start().  Either way, this initialization
overwrites the value used when sdp is defined.

This commit therefore drops this pointless definition-time initialization.
Although there is no functional change, compiler code generation may
be affected.
