Arnaldo Carvalho de Melo e4a338d05d perf top: Don't stop if no kernel symtab is found
We now just warn the user about the fact and go on providing just
userspace samples.

This fixes a problem when no vmlinux is explicetely passed by the user,
thus symbol_conf.vmlinux_name is NULL, no suitable vmlinux is found, and
then we get:

 aldebaran:~> perf top -p 7557
 [kernel.kallsyms] with build id 44d9a989eabbd79e486bc079d6b743d397c204e0
 not found, continuing without symbols
 The (null) file can't be used
