While testing building with libunwind (using LIBUNWIND=1) in various
arches I noticed a problem on arm64, on an rpi5 system, a missing close
parens in a change related to dso__data_get_fd() usage, fix it.

Fixes: 5ac22c35aa8519f1 ("perf dso: Use lock annotations to fix asan deadlock")

Thanks for fixing this.  For some reason the build test couldn't detect
it on my system (I have libunwind-dev installed).

I'll add it to perf-tools tree.

Thanks,
