perf annotate TUI browser: Do not use member from variable within its own initialization
Some compilers will complain when using a member of a struct to initialize another member, in the same struct initialization. For instance: debian:8 Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0) oraclelinux:7 clang version 3.4.2 (tags/RELEASE_34/dot2-final) Produce: ui/browsers/annotate.c:104:12: error: variable 'ops' is uninitialized when used within its own initialization [-Werror,-Wuninitialized] (!ops.current_entry || ^~~ 1 error generated. So use an extra variable, initialized just before that struct, to have the value used in the expressions used to init two of the struct members.
