[PATCH manager 0/1] pve8to9: fix package lookup empty result check

[Kefu Chai <k.chai@proxmox.com>]

I am new to Perl and noticed this while reading the code. I verified the
bug with a small test:

  perl -e '
    my $pkgs = [ grep { 0 } (1,2,3) ];
    print "Defined\n" if defined $pkgs;
    print "Zero\n"    if $pkgs == 0;
  '

Output:
  Defined

'$pkgs == 0' printed nothing -- the array reference is never numerically
zero, so the empty result check silently passed through even when the
grep returned no results.
