Thank you for the patch. It does indeed look pretty obvious.
You're patch did not apply for some reason, but since it was so
simple, I just redid it, bearing in mind Sergio's comments.
I then re-ran the testsuite on x86_64-linux to make sure it doesn't
cause any regression.
Attached is what I ended pushing (as both obvious and under 'tiny
patch' rule, meaning that you don't need a copyright assignment
for this change). If you are interested in contributing more patches
to GDB, you'll need a copyright assignement in place with the FSF.
Let us know and we will get you started; the process can be somewhat
lengthy.

Subject: [PATCH] frame.c: Fix the check for FID_STACK_INVALID in frame_id_eq()
I noticed in frame_id_eq() we were checking for the "l" frame_id being
invalid twice instead of checking both "l" and "r", so this patch
corrects it.
gdb/ChangeLog:
* frame.c (frame_id_eq): Fix the check for FID_STACK_INVALID.
