perf top: Use __fallthrough
commit 7b0214b702ad8e124e039a317beeebb3f020d125 upstream.
The implicit fall through case label here is intended, so let us inform
that to gcc >= 7:
CC /tmp/build/perf/builtin-top.o
builtin-top.c: In function 'display_thread':
builtin-top.c:644:7: error: this statement may fall through [-Werror=implicit-fallthrough=]
if (errno == EINTR)
^
builtin-top.c:647:3: note: here
default:
^~~~~~~
