perf lock: Fix option value type in parse_max_stack

Browse Source 
[ Upstream commit cfaade34b5 ]

The value is a void* and the address of an int, max_stack_depth, is
set up in the perf lock options. The parse_max_stack function treats
the int* as a long*, make this more correct by declaring the value to
be an int*.
