perf strbuf: Remove redundant va_end() in strbuf_addv()
commit 099be748865eece21362aee416c350c0b1ae34df upstream.
Each call to va_copy() should have one, and only one, corresponding call
to va_end(). In strbuf_addv() some code paths result in va_end() getting
called multiple times. Remove the superfluous va_end().
