qcacld-3.0: Fix TSO seg cookie init crash
In one of the recent fixes, we are setting the TSO seg contents to zero
when the segment is added back to the free list. The segment cookie is
not re-initalized at this point. Hence, when this segment is
re-allocated, it fails the cookie check and there is a system crash.
Fix the issue by re-initializing the segment cookie after zero-ing out
its contents.
