Revert "gdb: support zero inode in generate-core-file command"

Browse Source 
This reverts commit 1e21c846c2.

This change was causing unexpected mappings to be included in the core
files generated by GDB, which was triggering warnings when GDB opened
a core file, like this:

  warning: Can't open file [stack] during file-backed mapping note processing

  warning: Can't open file [vvar] during file-backed mapping note processing

For now I'm reverting the above commit and will come to the list again
when I have a solution that addresses the original issue without also
including the unexpected mappings.
