Adrian Salido 7e85a4b796 ANDROID: tracing: fix race condition reading saved tgids 
Commit 939c7a4f04 ("tracing: Introduce saved_cmdlines_size file")
introduced ability to change saved cmdlines size. This resized saved
command lines but missed resizing tgid mapping as well.

Another issue is that when the resize happens, it removes saved command
lines and reallocates new memory for it. This introduced a race
condition when reading the global savecmd as this can be freed in the
middle of accessing it causing a use after free access. Fix this by
implementing locking.
