[PATCH] trace: remove unneeded initialization in __trace_uprobe_create()

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

There is no need to initialize ret with 0, as all the early error branches
simply return constant values, and the default path always reaches
ret = kern_path(filename, LOOKUP_FOLLOW, &path), which will reset ret
before the initial value was ever used.

Remove this unneeded initialization and keep the code succinct.
