[PATCH] fgraph: fix unused value in register_ftrace_graph()

[Gianfranco Trad]

Coverity reports unused assignment to value ret. [1]
ret is assigned to 0 here, but that stored value is overwritten before
it can be used. The overwrite might happen either at line 1277, 1290 
or eventually at line 1306. Therefore, cleanup the unused assignment.
